IELTS TASK 1 WRITING: GROUPING DATA

IMPORTANT INFORMATION ABOUT GROUPING DATA
Here is the graph from yesterday’s question showing the percentage of people using various forms of transport in the past month (note: people often used more than one mode of transport)  but the overview has been written in a slightly different way.
trends02

“Overall, the proportion of people making a journey by car underwent a dramatic increase over the period shown while the percentage of people who travelled by bus and bicycle fell significantly. In addition, the popularity of travelling by train declined initially and then rose, although it did not reach the level it had at the start.”

I see many students say the data can be divided into a certain number of groups in the introduction and then just mechanically go through the data as it is presented without actually grouping it in the organisation of the essay.

Some teachers tell students to write a sentence like:

“It is immediately obvious that this data can be divided into three groups.”

But then they fail to teach their students to actually use this grouping in the organisation of the essay i.e. write about EVERYTHING THAT INCREASED, then write about EVERYTHING THAT DECREASED and finally write about EVERYTHING THAT STAYED STEADY (or dipped or peaked or whatever else the data shows).

If the candidate writes that: “the data can be divided into 3 groups” but then simply goes through the data in the order it is given, making no attempt to GROUP it, they should not expect a high score. It is NOT LOGICAL to write about something that increased, then something that decreased, then something else that increased, then something that stayed constant and finally something that decreased.

This is not useful and would very likely cause a lower band score. Look at what the IELTS Public Band Descriptors have to say about this:

BAND 7 (Coherence and cohesion): logically organises information and ideas
BAND 5 (Task Achievement): recounts detail mechanically

A logical approach would GROUP the data into what increased, what decreased and then what remained constant, for example, and deal with ALL items that belong to each group in the appropriate section.

DON’T JUST SAY THE DATA CAN BE GROUPED, structure your essay to clearly SHOW the grouping.

If you look back through every big picture description we have written over the last month, you will notice that we did this EVERY TIME. Personally, I would never waste my time to write that the data can be grouped into 3 groups (or whatever number is shown in the data) although it is not wrong to do it, instead, I would structure the essay to demonstrate that these groups exist in the way done in the overview given here.

IELTS TASK 1 WRITING: THE BIG PICTURE – COMPLEX TRENDS

Over the past month we have covered many important aspects of Task 1 IELTS writing and today I want to discuss a complication that can occur with the trends that can occur.

Look at the graph shown here that covers the period from 1990 to 2010 and shows the percentage of people using various forms of transport in the past month (note: people often used more than one mode of transport). THIS IS NOT A REAL QUESTION! It has so many bars in order to show the trends very clearly.
trends01

As in an example we looked at recently, the trends have some variation but the general trends are very clear.

“The percentage of people who travelled by bus fell significantly over the period shown while the proportion of people making a journey by car increased very dramatically.”

This should be getting quite simple now. BUT … what about train travel?

Train travel decreased overall if you compare the percentage of people who travelled by train in 1990 to the proportion who travelled in 2010, but the story is actually more complicated than this and the size of the fall (around 40%, in relative terms, is too big to ignore). A more detailed response might say:

“In addition, the data also shows that the popularity of train travel fell in the first half of the period and then began to increase although it did not reach the same level that it had in 1990.”

The candidate must make the decision about whether the size of the dip is big enough to worry about and this will depend on the data given in the question.

Look at the more realistic example in the second bar graph which also shows the percentage of people using various forms of transport in the past month (note: people often used more than one mode of transport).
trends02

The trends for Bus and Car transport are very clear, the problem areas are the trends for train and bicycle use. The very big picture in both cases is that the proportion of people using these methods fell overall BUT the dip in train travel for 2000 is too significant to simply ignore. In the case of bicycle use the slight rise in the final year is not so significant and it could be ignored in giving a very brief picture of what happened.

IN BRIEF
One way to write the big picture view here might be:

“The percentage of people who travelled by bus and bicycle fell significantly over the period shown while the proportion of people making a journey by car increased very dramatically. In addition, the proportion of people travelling by train fell initially and then rose, although it did not reach the level it had at the start.”

IN SHORT
Candidates must look at the data when this sort of thing occurs and decide if the irregularity is big enough to talk about, as in the case of Train travel, or if it is small enough to ignore, as in the case of Bicycle travel.

IELTS TASK 1 WRITING: THE BIG PICTURE – ONLY MAGNITUDES

Today we will look at an example where the teachers who tell students to look for the key features by looking only for what is big and small are actually correct. HOWEVER, it is very, very important to understand that this is not always the case, as we saw in the dramatic examples of the past 2 days.

This bar chart represents the water use given in percentage in a number of different regions in 1995.
Water use08a

THE BIG PICTURE
The horizontal axis just has a list of regions, which does not allow us to identify a trend. However, there is more than one way to group this data, for example, we could look for a big gap between Agricultural water use and Industrial water use (Africa, Asia, Latin America) and those regions where there is a small gap (North America and Europe). We can also do it just by looking for the regions where Agricultural use is high and those where Industrial use is high. It makes no difference which way we do it.

AGRICULTURAL WATER USE HIGHEST
Africa
Asia
Latin America

These regions also had a very low use of water for industrial and domestic purposes

INDUSTRIAL WATER USE HIGHEST
North America
Europe

In these regions domestic water use accounted for the lowest level of consumption with Agricultural use a little lower than industrial use . In fact, it was about 15% lower in North America and 33% lower in Europe, in relative terms. We will look at how to calculate these figures later as we have mentioned “relative terms” many times over the last month.

One way to write the big picture view might be:

“Overall, Agriculture accounted for the highest amount of water use in Africa, Asia and Latin America while use of water for Domestic and industrial purposes in these regions was very low. In addition, the data shows that Industrial use of water was highest in North America and Europe with the proportion of water used for Agriculture a little lower and Domestic use very low in both countries.”

IN SHORT

When you look at this bar chart, it almost looks like there are trends shown BUT when you look carefully, you realise that no trends can be identified here and you must find another way to group the data. (If this chart is drawn to show the regions in order of their use of water for Agriculture, it is very easy to get trapped and think there is a trend).

Water use08

After trends, we always look to see if we can describe differences in MAGNITUDE and in this example, that is exactly what we do.

Notice that we DO NOT USE NUMBERS in the big picture statement. We do not want to confuse the reader and make them think we are giving details for the graph, so we avoid using numbers BUT in these magnitude questions, this can lead to language that is not entirely precise e.g. “a little lower”. Nevertheless, we will solve this issue in the details section by giving very precise information about the magnitudes we are describing.

IELTS TASK 1 WRITING: THE BIG PICTURE

Here is another example where candidates can easily make errors although this one is presented in a way that the situation should be fairly clear.

This graph shows the distance covered in millions of passenger kilometres in one city in China.
transport01

MAGNITUDES
It is quite difficult in this question to say too much about the magnitudes because most of them are changing all the time. It would be possible to average the values and make some general comment but this is perhaps more of a detail than a key feature EXCEPT for the position of walking as a means of transport. Very clearly, walking did not account for a high number of kilometres and it is the smallest by comparison to all other modes of transport and, finally, the distance covered by this method has not changed significantly over the period.

TRENDS
A large number of bars are given here, representing 6 different years. Hopefully, you can see that even though there is some irregularity present in all modes of transport, except for the train, the trends are still very clear.

Sometimes candidates concentrate too much on details and will talk about the increase in bus or bicycle travel between 1990 and 1995 BUT these points, while true, are an extremely minor detail in the use of each of these methods of travel.

The most important feature here is the very clear trends that are shown and not every little variation in the heights of the bars. The data shows very clear general trends in the distances traveled by each mode of transport.

THE BIG PICTURE
One way to present the big picture view might be:

“Overall, the distance covered by train and car increased significantly over the period shown while that covered by bus and bicycle saw a large decline. In addition, the distance covered by walking remained fairly steady in comparison.”

When you look at the bar charts for bus, car and bicycle travel don’t get tricked into concentrating on the individual bars. Look for the BIG PICTURE. A lot of candidates would say that bicycle use fluctuated BUT this is NOT CORRECT. Although the distances covered by bicycle were a little erratic, there was a very clear downward trend and THAT IS THE BIG PICTURE.

NOTE: THE USE OF THE WORD “POPULARITY”
Many candidates would use the word “popularity” in responding to this task HOWEVER a careful analysis shows that we don’t know how popular these modes of transport are with people in the city. Look at walking as an example. According to the graph, around 8 million kilometres are walked every year by people in this city. This could happen if very large numbers of people are walking short distances OR if a much smaller number of people are walking quite big distances. There is nothing in the data that tells us how many people walk, consequently, the POPULARITY of these modes of transport is unknown. In short, we really should avoid using this language if we want to be very precise in the response.

IELTS TASK 1 WRITING: TWO GRAPH TASKS

Here is another 2 data set question based on real data.

The first data set is a line graph showing how satisfied people are with life as they age.

life satisfaction01

The second data set is a bar chart showing happiness and GDP per person (this is not the income of each person but the overall wealth of the country averaged across the entire population)

life satisfaction04

THE BIG PICTURE
LINE GRAPH
The trends for men and women are quite similar except that teenage males are more satisfied than females although from the age of 20 onwards, the trends are almost identical with satisfaction falling steadily until mid-life and then rising substantially as people get older.

BAR GRAPH
The bar chart data is very interesting because even though a list of countries like this may not be expected to show a trend that can easily be described, the data allows us to identify wealthy and poor countries (the GDP figures) – in an IELTS exam candidates are not expected to know this. Once the rich and poor countries have been identified, I can also identify a general trend and that is that people tend to be happier in poor countries and less happy in rich ones. (Note that this is actually a real and quite general trend and it is seen in many more countries than listed here).

I have to say that this is a GENERAL TREND because it is not completely true. For example, Australia has a lower GDP than the USA but its people are not much happier and India has a much lower GDP than Mexico but its people are slightly LESS happy. Nevertheless, as can be seen from the heights of the bars in the bar chart shown here, it is generally true that as the GDP increases, people are less happy. Remember, this is the BIG PICTURE and I do not have to worry about very minor variations.

THE BIG PICTURE
Here is one way to write the big picture statement:

“Overall, while people become less satisfied until middle age, satisfaction then rises substantially as they age and with the exception of teenagers, the trend is almost the same for men and women. The data also shows that people tend to be happier in poorer countries and less happy as the wealth of the country increases.”

and IPSOS Nov 2011 survey/IMF (bar chart))

IELTS TASK 1 WRITING: TWO GRAPH TASKS

We have mentioned two graph questions briefly before but today we will look at writing the “big picture” for one of these tasks.

This is an example from the “COMPLETE IELTS” series published by Cambridge University Press.

A table of data gives this information:

Internet use in Australia – 2008
Banking ………. 62%
Phone calls ……22%
Blogs ……..……10%
Good/services….57%
Bills ……………..63%

The bar graph shown here also shows the percentage of Internet use in Australia by age group.
twocharts01

The approach to this type of question is to check first how the data connects in the two data sets. Here there is no direct comparison that we can make because the data is different: the table shows Internet use and the bar chart shows who uses it.

1 TABLE
MAGNITUDES
Big differences in magnitudes are shown in the tale and that is how we will group this data.

The biggest areas of use shown in the table are:
Bills
Banking
Goods/Services

So we could sum this up by calling it “financial activities” because the three items all refer to some activity related to money.

2 BAR CHART
TRENDS and MAGNITUDE
The first thing we notice is that there are no years on the data so we cannot find a trend in years BUT the bar chart does have AGE GROUPS and can see that while Internet use is very high across all age groups, with the exception of the oldest group, a slight downward trend is indicated for people over 20-29.

Note that this trend is so slight, with the exception of the oldest group, that it would be perfectly acceptable to simply say:

“Internet use was very high across all age groups, except for the oldest group.”

THE INTRODUCTION
In the past few weeks, we have concentrated on the big picture, but in this example I will begin with the introduction because it shows how to deal with these two data set questions. The introduction simply has to say what is shown in the first data set and then what is shown in the second. Here is one way to it:

“The table gives information about Internet us in Australia while the bar chart indicates the percentages of people who use the internet by age group.”

THE BIG PICTURE
One way to write the big picture view might be:

“Overall, the Internet was used most for financial activities and while Internet use is very high with all age groups, it was less popular with older people.”

IELTS TASK 1: MATHS QUESTION TYPES

Let us take a break from comparison questions today because we have done quite a bit over the past week.

One issue that troubles many candidates who take classes is that often the teacher doesn’t cover all the different types of maths question: bar charts, line graphs, tables and pie charts. In our classes we do manage to cover all these types and additional issues with maths questions but the truth is, most of the times, candidates don’t have to worry. None of these different types create any special sort of problem: no matter how the data is presented you are basically looking for two things – TRENDS and MAGNITUDE differences.  As we have seen, sometimes only the trends matter, sometimes only the magnitudes matter and OFTEN BOTH matter.

But the way the data is presented usually makes no difference. Let us look at an example of this.

BAR CHART
Here is a bar chart which presents information comparing the percentage of household spending in a number of different areas:

spending_bar

TABLE
But look at this data:

Item ……………………1955….1985….2015
housing ……………….33 ……..18 ……14
electricity & water ….18 ……..21 ……28
Food …………………..15 ……..18 ……10
education …………….20 ……..24 ……30
holidays ………………..8 ……..11 …….8
entertainment ………..6 ……….8 …….10

As we will see in a minute, the same information is contained here.

PIE CHART
and finally look at this data:

spending_pie1

spending_pie2

spending_pie3

These pie charts again contain exactly the same information as the table and the bar chart.

NOTE:
Although we could draw a line graph for this data, it would not really be very sensible because we only have annual figures for three years. If we had annual data for many years, then it would be more meaningful to use a line graph with a continuous line from year to year. Nevertheless, you will understand the point being made here that the type of data presented makes no basic difference to the way you must answer the question.

THE BIG PICTURE
This same analysis can be made from any one of the data sources presented here. Although quite a lot of data is presented, in principle, it is not difficult.

1. TRENDS
Years are presented on the data so we can look for trends:

INCREASE IN PERCENTAGE OF SPENDING
electricity & water
education
entertainment

DECREASE IN PERCENTAGE OF SPENDING
housing
food

FAIRLY STABLE (in fact, it actually PEAKED)
holidays

PEAKED: DETAIL OR NOT
Note this last category is not really just stable, there is more to the story than this. In this case, the percentage of spending rose to a peak and then fell back. Is this important? Well, in general, it depends on the data in the question. Here an increase of around 35%, in relative terms, is followed by a decrease of around 27%, in relative terms, so these changes are not huge but they are not insignificant. This is a judgement that needs to be made from question to question when you see peaks, and also dips, in Task 1 Writing questions.

2. MAGNITUDES
The magnitudes can easily be mentioned in the question as part of the description of trends, perhaps with the exception of the proportion of spending on holidays and entertainment, which saw the lowest proportion of spending, and we can deal with that very simply in a single RELATIVE CLAUSE as done in this sentence.

IN BRIEF
One approach to writing the overview might be:

“Overall, the proportion of spending increased significantly on electricity & water, education and entertainment over the period while it saw a decrease for housing and food. In addition, the percentage of expenditure on holidays was relatively stable, in comparison to most other items.”

Note that it would be possible to replace this last sentence with:

“In addition, the percentage of expenditure on holidays rose to a peak and then fell back.”

this is entirely accurate and it really doesn’t take any longer to write IF you realise that this somewhat erratic behaviour has occurred.

IN SHORT
The way the data is presented really makes no difference to the way candidates must approach the question. The big picture statement above is the same no matter how the data is presented and the ‘Details” section, which would come after this would also be the same.

IELTS TASK 1 WRITING: COMPARISON TASKS, BIG PICTURE

Here is another comparison question but in this case there are no huge differences between boys and girls so we look at a very simple way to group the data. This data also has an interesting addition:

1 The WORLD AVERAGE. When given information about averages or overall totals, candidates must be careful to take this information into account. These averages are almost always important.

2 It looks like there is more than one way to organise the data, but candidates must be very careful when this occurs to make sure you are targeted on the purpose of the data and don’t interpret the data in a way that hides its most significant feature.

This data compares the percentage of secondary age children in various regions who attended secondary school in 2005. (e.g. If a region has 100 secondary aged children but 45 of them work and 55 go to school, then 55% of secondary aged students go to school.)
School enrolment - secondary

DON”T MISS IMPORTANT INFORMATION IN THE BIG PICTURE
It might be tempting here to group this data by magnitude. It certainly looks like you could – what is high, what is in the middle, what is low.

The problem with this is that if you only group by magnitude, you lose a very significant aspect of the data and that is the regions in which the percentages of boys and girls attended secondary school AND when you think about it, this was the whole purpose of the data in the first place. So if a candidate did not raise this issue at all and just talked about the overall magnitudes of secondary school attendance, there is a very good chance they could face a problem that is raised in the PUBLIC BAND DESCRIPTORS at BAND 4 level under TASK ACHIEVEMENT:

• may confuse key features with detail

The only way to be sure that the key features have been covered here would be to present the important information about the differences in male and female enrolments AND in the process of giving the details for this comment on the different magnitudes in enrolments.

KEY FEATURES
PROPORTIONS OF MALES AND FEMALES ABOUT EQUAL
Industrialised countries
East Asia and Pacific

PROPORTIONS OF MALES HIGHER THAN FEMALES 
Middle East and North Africa
World average
West and Central Africa

PROPORTIONS OF FEMALES HIGHER THAN MALES 
Latin America and Caribbean

Notice that the World average is included in one of these groups and can also be used to compare which regions are above and below this average. This gives an important benchmark for how a region is doing compared to the rest of the world and this is why average figures like this can never be ignored.

THE BIG PICTURE
The big picture for this data might look like this:

“Overall, approximately equal percentages of boys and girls attended secondary school in the Industrialised countries, where all school aged children went to school, and East Asia and the Pacific while a higher proportion of girls than boys went to school in Latin America and the Caribbean. In addition, the data also shows that a higher percentage of boys than girls were enrolled in high school in the Middle East and North Africa, the World average and West and Central Africa, which had the lowest level of school enrolments of all regions by far and was the only region below the world average.”

This is a very complete overview and it is targeted on the key feature of the comparison between enrolments of boys and girls although it also raises some of the other notable features.

IELTS TASK 1 WRITING: COMPARISON TASKS

Here is a more common type of comparison task.

This graph shows the participation rates in sports in Canada in 2005.
Sport in Canada02

Notice that there are very big differences in the participation in some sports and very little difference in the participation in others. For example:

BOYS PARTICIPATE MUCH MORE THAN GIRLS IN:
Ice Hockey
Golf

GIRLS PARTICIPATE MUCH MORE THAN BOYS IN:
Swimming
Volleyball

BOYS AND GIRLS PARTICIPATE AT ABOUT THE SAME LEVEL IN:
Cycling
Tennis

IN BRIEF
Here is one approach to writing the ‘big picture’ statement:

“Overall, boys participate in Golf and Ice Hockey far more than girls while Swimming and Volleyball are far more popular with girls than boys. In addition, the data also shows that participation in both Cycling and Tennis is approximately equal.”

The way we have grouped the data is by realising that there are big differences between some participation rates for boys and girls and very little difference for others. Note that we DON’T just look for a BIG GAP, if we did that we would mix up the boys and girls, we look for a big gap where boys have the greatest participation and a big gap where girls have the greatest participation. Finally we look for sports where this gap is not significant between the boys and girls. This provides a very simple and logical way to group the data.

Note that the sports with almost equal participation really are very close together but even if there were a slightly greater difference, it would have still been put in the group that showed the difference was not very big. For example, the figures for soccer could have been used in this graph where the participation for boys and girls was:

boys …. 9%
girls …. 11%

Although the participation of girls is higher than boys, it is NOT very much higher so It would be put in the group of almost equal participation.

IELTS WRITING TASK 1: COMPARISON TASKS

This bar chart shows the literacy rates of males and females in various countries around the world in 1990.
literacy rates01

  1. No years are shown on this data and no other variable, which could show a trend, is present. Consequently, the data must be grouped in other ways.
  2. What stands out is that BOYS HAVE A HIGHER LITERACY RATE THAN GIRLS IN EVERY COUNTRY. This is important because it actually stops us from using the normal strategy for this type of question which is to group the data by looking at where the number for boys is greater than girls, where the number for girls is greater than boys and where the numbers for boys and girls are about equal. This was the method we used yesterday.
  3. What is noticeable is that in some countries there is almost no gap, in others the gap is somewhat bigger and in some countries the gap is very big. The reason this method will work here is BECAUSE the boys literacy rate is ALWAYS higher than the girls.
  4. Notice that magnitude differences are also shown here with South Africa and Brazil having, in general, the highest average literacy rate followed by Turkey and Kenya with Pakistan and Mozambique clearly having the lowest overall average literacy rates.

GROUPING
Literacy rates about equal:
South Africa
Brazil

Medium gap between boys and girls:
Turkey
Kenya

Large gap between boys and girls:
Pakistan
Mozambique

IN BRIEF
One way to write the big picture view here would be:

“Overall, boys have a higher literacy rate than girls in every country shown although the rates are almost equal in South Africa and Brazil where the average rates are higher, in general, than other countries given. In addition, the literacy gap is significantly higher between boys and girls in Turkey and Kenya while Pakistan and Mozambique have the highest literacy rate gap of all countries and these two countries have the lowest overall literacy rates.”

This is a complex overview statement but it covers all the key features shown in this data.

Grouping data by the size of the gap only really works because the literacy rate for boys was higher than girls in every country shown. Grouping the data this way wouldn’t be successful if the literacy rate for girls was sometimes higher than that for boys.

IELTS TASK 1 WRITING: COMPARISON TASKS

We will talk more about the big picture in magnitude and trend questions later but today I want to discuss the third major type of mathematics Task 1 – COMPARISON TASKS.

These tasks, often presented as bar graphs or a table, have the distinctive feature that they compare two things e.g. male and female performance in exams; participation by boys and girls in a range of sports, popularity of different kinds of foods with males and females; popularity of various websites with men and women, percentages of students attending primary school compared to the percentage going to secondary school to mention just a few possible examples.

In the case we will look at today, the graph shows the attitudes to the use of Information Technology (computers and the Internet) in education.

IT use in schools

1. GROUPING THE DATA
Notice that no years are available in this data and there is no other item in which we can find a trend. So the strategy here will be to look at where do a higher percentage of girls hold an opinion and then look at where do a higher percentage of boys hold an opinion and finally we will look where do about the same percentages of boys and girls hold an opinion.

GIRLS HIGHER THAN BOYS
Improves learning

BOYS HIGHER THAN GIRLS
Improves productivity
Attracts students

BOYS AND GIRLS ABOUT EQUAL
Easy library access
links socially

2 MAGNITUDE OF OPINION
Notice that some opinions are more popular than others. For example , boys and girls think that access to IT is easy in the library while only half this percentage think that IT is able to link people socially. This is a detail and would not be mentioned in the “OVERVIEW STATEMENT”, it would be mentioned in the “DETAILS” paragraph.

IN BRIEF

“Overall, a higher proportion of girls thought that IT access improved learning while a higher percentage of boys than girls believed that IT improved productivity and attracted students. In addition, the data also reveals that equal proportions of boys and girls believed there was easy access to IT in the library with an equal although much lower percentage who believed it aided social links.”

Another, very simple, way to report that there was no difference between boys and girls on the other issues would be:

“In addition, the data also reveals that in their views on other issues, gender differences were not apparent.”

In this case the information about the higher popularity of the view about the library and the much less popular view about IT assisting social links would be left to the “Details” part of the essay.

IELTS TASK 1 WRITING: Trends & Magnitudes

Tomorrow we will move on to discuss the third major type of mathematics questions – COMPARISON TASKS but today I want to look at a question which you should no longer find very difficult.

The graph shows the percentage of government spending on public schools in inner city areas as a proportion of the whole city education budget. (NOTE: this data is not real!)
public schools01

1 TRENDS
The first thing the candidate should notice here is that the data has years. This means you can find trends in the data. These trends exist even though the data is a little erratic. You must be very careful about this: do not ignore a trend just because the data jumps around a little.

INCREASE:
Australia
Canada

DECREASE:
New Zealand

NO SIGNIFICANT CHANGE:
Norway

2 MAGNITUDES
The candidate should also notice that the proportion of spending in Australia was far higher throughout the entire period than spending in the other countries. Similarly, New Zealand spending was IN GENERAL lower than spending in other countries. This should be noted in the response.

IN BRIEF
A big picture view of this data might look like this:

“Overall, although the proportion of spending rose significantly in Australia and Canada, it fell in New Zealand and remained fairly steady in Norway. The data also shows that the highest level of spending occurred in Australia while the lowest, in general, was in New Zealand.”

The reason the words “in general” are added here is that if you look at the proportion of spending in the first two years, New Zealand spending is not actually the lowest (Canadian spending is lowest) but New Zealand spending is not much higher and it is significantly lower in all the following years.

This is a very complete response to the main features of the data and was not too difficult to do.

SUMMARY
The most important thing that candidates should realise when they look at an IELTS WRITING TASK 1 is that both TRENDS AND MAGNITUDES should be considered as possible summaries of the data. We have seen examples where sometimes ONLY THE TREND is important and we have seen other examples where ONLY THE MAGNITUDES are important but there are many, many questions where BOTH TRENDS AND MAGNITUDES are significant. Nevertheless, if you know this when you go into the exam, questions like this one should be fairly easy.

IELTS TASK 1 WRITING: SIMPLIFYING COMPLEX DATA

We have looked at some quite difficult questions over the past few days and here is one more although after yesterday , it may not look so difficult!

The table gives information about energy generation in a number of different countries:

electricity generation01

The problem again is the amount of data that is here. What is the BIG PICTURE?

  1. The first thing we should notice is that there is NO TREND in this data so we will look at the differences in magnitude.

Looking at the total energy production in the last column we see that we can group the data like this:

HIGHEST PRODUCTION: (around 500 KwH)
Germany
France

MEDIUM PRODUCTION: (around 300 KwH)
UK

LOWEST PRODUCTION: (around 150 KwH)
Spain
Norway

Note that the countries have been listed in order of magnitude within each of these groups.

2. We should also comment on the major sources of electricity with about equal amounts coming from Thermal and Nuclear with much lower levels from Hydro and very little from Geothermal.

The BIG PICTURE overview might look like this:

“Overall, Germany and France generated the highest amount of electricity while the UK generated a significantly lower amount and the smallest levels of electric were produced in Spain and Norway. The data also shows that the five nations produce about equal amounts of electricity from Thermal and Nuclear energy whereas a much lower proportion of is generated from Hydro with only a minor contribution from Geothermal.”

This is a quite an extensive overview that covers both major aspects shown by the data.

Note that the details about where each country got their energy would be covered in the ‘details’ part of the essay but that this should be mentioned because there are some very significant differences:

Germany (Thermal 60%; Nuclear 30%)
UK (Thermal 60%; Nuclear 25%)
Spain (Thermal 50%; Nuclear 25%)

France (Nuclear – around 75%)

Norway (Hydro about 99%)

IELTS TASK 1 WRITING: SIMPLIFYING COMPLEX DATA

Sometimes there is so much detail in the data that some of it MUST be ignored so that the response can be written in 150 words in no more than 20 minutes. HOWEVER, YOU MUST BE VERY CAREFUL ABOUT THIS. You cannot ignore KEY FEATURES – what we are talking about here is ignoring some of the less important detail in order to give the most important information that is shown.

This is really not just an exam requirement. If you want people to understand the most important features of the data, the essay should not be full of a whole lot of less important detail. If you only write about the most important features, the essay will be very easy to follow.

Here is a quite difficult task, which is a real past IELTS exam question. (I must thank one of my past students, Kotchaphop Kornphetcharat, for this question as he sent it to me as part of his preparation for the IELTS Exam.)
prisoners01

  1. The first thing that the candidate should see in this question is that there are years in the data. This means you can look for trends.
  • Increase in prisoner numbers:
    Great Britain
    USA
  • Decrease in prisoner numbers:
    Canada
    New Zealand
    Australia

Note the the order of the countries listed here is not an accident, they are grouped in order of the magnitude of the number of prisoners, this creates a very logical structure to the response and is NOT just a mechanical listing of the countries in the order they are given in the data. Remember in the IELTS WRITING PUBLIC BAND DESCRIPTORS under TASK RESPONSE, it says:

Band 5:  recounts detail mechanically

Our response is NOT mechanical because we have grouped the data into what went up and what went down as well as then grouping the data WITHIN those groups in order of magnitude.

The problem with this question is that when you look at the data for New Zealand and Australia, you see that it is really quite complex: in New Zealand the data fell sharply at first and then rose throughout the remainder of the period although overall prisoner numbers DID FALL over the whole period. Similarly, in Australia, it is even worse where numbers plunge at first then rise and then plunge again. Nevertheless, overall the prison population DID FALL in Australia despite the erratic trend.

I could write about all this detail but it would significantly increase the length of the essay and the time it would take to write it. These variations in numbers are details rather than key features and so I will ignore them when I write my response. I do, however, make a reference to this problem by saying “… although it was erratic in Australia and New Zealand.

“Overall the numbers of people who were sent to prison increased significantly in Great Britain and the USA over the period shown while imprisonment in Canada, New Zealand and Australia witnessed a decline although it was irregular in Australia and New Zealand.

Note that if I had the time, I would write about some of this detail but if I write all this detail in the ‘details’ part of the essay, my essay will end up being around 250 words in length!

IELTS TASK 1 WRITING: TOO MUCH DATA

If you are faced with a simple question where the data is not very complex, IELTS Task 1 Writing can be very simple. Unfortunately this is not always the case and sometimes candidates can be faced with very complex questions. Of course, this is also true in real life where data can look very complex at first.

The ‘trick’ and the task of candidates in an IELTS WRITING exam is to identify the KEY FEATURES of the data. Here is an example where there is more information than we really want to see in an IELTS TASK 1 WRITING:
foreign students01

1. The first thing we should notice is that there are years given in the table, which means we can look for trends. If we look at the three destination countries we see that student numbers increased in every country:

Australia: more than doubled from 10,000 to over 22,000
USA: increased by almost 4 times (from more than 4,000 to almost 16,000)
China: increased by a little more than 2 times (from about 6,000 to more than 13,000)

2. However there are other important details here that have nothing to do with the trends and that is the fact that Australia has more students than either the USA or China. (Student numbers in Australia in 2011-12 were about 30% higher than in the USA and a little over 50% higher than in China.)

3. If we now look at the percentage change in student numbers we see something extremely important: the numbers in Australia decreased in the last two years shown while in the USA and China the numbers continued to increase. Note that while the final year is not given for China the numbers were still going up year-on-year at least up until 2011 when the numbers in Australia had already started to fall.

So the big picture view might look like this:

“Overall, the number of Vietnamese students who studied in the three countries shown increased very significantly over the period shown although most students chose to study in Australia. In addition, the data also shows that the popularity of Australia over the last two years given decreased while the popularity of the USA and China continued to increase.”

This is a fairly simple summary of what is really quite complex data. When faced with an IELTS TASK 1 WRITING question, always look for the BIG PICTURE and you will find that it does’t matter if you get a hard question with a lot of data, you will still be able to identify the most important aspects of the information.

BUT

… as you can see in this example the big picture may involve BOTH trends AND the MAGNITUDE of the quantities shown and you must look carefully to see the you include all the most important aspects of the data.

Note also that sometimes it is simply not possible to talk about all the details shown and we will look at one of these examples next time.

IELTS TASK 1 WRITING: MAGNITUDE & DOUBLE GRAPH TASKS


Here is another example of a magnitude task. These should be getting easy now.

The pie chart shows U.S. Greenhouse Gas Emissions from1990 to 2012.
magnitude03

Even though we know the years that this data apples to, there is no time scale in this data, so we cannot identify a trend. The procedure is therefore to group the data by magnitude:

High (22%)
Space cooling

Medium: (around 10-12%)
Other
Lighting
Electronics
Space heating/water heating/Refrigeration

Low: (around 5%)
wet cleaning
Cooking
Computers

So the BIG PICTURE would be:

Overall, the greatest single contribution to green house gases was caused by Space cooling while a much smaller amount of gases was created by Other, Lighting, Electronics, Space heating, Water heating and Refrigeration. The data also reveals that by far the smallest volume of gases was produced by wet cleaning, Cooking and Computers.

This is all quite simple now, BUT, there is some REALLY BAD NEWS!

It is not likely that you will get a single pie chart like this in the IELTS writing test. What is much more likely is that the pie chart in todays question will come with the pie chart in yesterday’s question and you will need to write about both these pie charts in a single question.

This is not so difficult. It is really just two quite simple questions combined into one.

In your introduction you just say what is shown in the first pie chart and then what is shown in the second.

For the overview, you identify the most important features of the first pie chart AND the most important features to the second, exactly the same as we have done yesterday and today. This combination is the overall statement of the BIG PICTURE.

IELTS TASK 1 WRITING – TRAPS IN TRENDS

Be careful when you look at data to define the trend accurately. Two problems come up frequently in IELTS writing, in fact, these issues are common in all statistical analysis.

Don’t be fooled by strong tends into thinking that a trend that is not so clearly as strong does not exist.

Look at the graph here that shows gives information about the popularity of the consumption of organic foods (foods grown without chemicals and fertilizers). There are clearly very strong upward trends in Australia and the USA but the trend in the UK may not appear strong at all by comparison. This is where a little mathematics can be extremely valuable.

Many candidates would say that consumption in the UK stayed fairly constant, BUT DOES IT?

Consumption rose from 10 to around 22 i.e. it more than doubled! This is a very significant rise and it should be mentioned. It would wholly incorrect to say that consumption was fairly steady in the UK – consumption doubled.

Look at the increase that occurred in Australia: start = 45; end = 92; rise = just over 2 times

The rise in consumption in the USA was even more significant: start = 25, end = 73 rise = around 3 times

In fact, all three countries show very significant increases in the consumption of organic foods in this data.

Sure! organic food was much more popular in Australia than it was in the UK and this is an extremely important point to make in your essay, but don’t be fooled into thinking the trend in the consumption in the UK is unimportant just because the figures were lower than for consumption in the other nations.

Don’t get tricked by the fact that the absolute value might be low. When you are looking at trends, it is the change that is important. Absolute values may also be important, as we see in the example today and also yesterday, but this is in addition to the importance of the trend.

Here is a sample overview for this question:

“Overall, he consumption of organic foods in the three countries show a very significant increase although the level of consumption was highest in Australia, followed by that in the USA with consumption in the UK the lowest of all nations.”

In the example yesterday and also in this one, we see a very important type of IELTS Task 1 question: in these cases it is NOT ONLY THE TREND that is important BUT ALSO THE MAGNITUDE differences between the items shown in the data. Be careful to include both in questions like this if you want to achieve a good score.

IELTS TASK 1 WRITING – TRENDS and MAGNITUDES

Over the past week we have looked at a range of Task 1 questions to see how we should write about “the big picture”. This is one of the most basic and important aspects of producing a good IELTS Task 1 essay.

To review the major point of the past few days, when dealing with a mathematics type question look to see if you can identify a trend and don’t fall into the trap of thinking that trends only occur with time. It is true that these are by far the most common types of trend both in the IETLS Writing Test and real life. But, as we have seen, there are extremely important trends in other variables such as age, income level, education level, fitness level and many other quantities.

When you face an IELTS Task 1 task look at the data to see if there is a trend in the data. It does not matter if it is a bar graph, a line graph, a table or a pie chart, all of these forms of data can be used to show a trend. Step 1 in writing a response is to check the data to see if it contains a trend. If the data has a trend, WRITE ABOUT IT in your essay.

But don’t get fooled: Despite the fact that this data contains years, the trends are very small and by far the most significant thing here is the huge differences in the types of accommodation that people use. (We will discuss magnitude differences in the next several posts.)

Percentage of Australians Living in Various Housing Types:

DWELLING STRUCTURE ………….2006 ………… %……….…..2011…….…… %
Separate house……………………5,472,527……….76.6………5,864,573………75.6
Semi-detached/terraced…………….658,858…..…….9.2…………765,978……….9.9
Flat/apartment………………………..932,862……….13.1………1,056,236………13.6
Other dwelling……………………..…..76,080…………1.1…….……66,666………..0.9

The trends that exist here are a very small increase in the percentage of people living in semi-detached houses and flats and the slight decrease in the proportion of people who live in separate houses.

These trends can certainly be mentioned and in a high level answer should be mentioned but the huge differences in the types of housing should also be a major part of the answer. So, an overview statement might look like this:

“Overall, while most people chose to live in a separate house, a very much smaller proportion lived in semi-detached houses and flats and the numbers choosing other dwelling types was extremely low. The data also reveals that there was a slight decrease in the proportion of people living in separate houses whereas the percentage living in semi-detached houses and flats saw a small increase.”

IN BRIEF

This is a complex question because although the trends here are not the most important thing, in a high level response they probably should not be ignored. Here the most significant issue is the percentages of people who chose particular dwelling types because the differences are very dramatic. Later we will look at questions where the magnitude differences are the only thing that is important but be aware that you will see many questions like this where BOTH TREND AND MAGNITUDE differences need to be discussed.
