IELTS Writing: Writing overview sentences

“In Academic Writing Task 1, it is very important to start by providing an overview of the data. If you don’t do this, you will lose points.”

Simon Cockell, Sultan Qaboos University, Oman

In this post we will look at what this means, and how you can use your data overview to get your IELTS Writing test off to a flying start.

What is Academic Writing Task 1?

Let’s start by going back to basics. In IELTS Academic Writing Task 1 is a “writing task of at least 150 words where the candidate must summarise, describe or explain a table, chart, graph or diagram.” Here’s an example (taken from Road to IELTS).

Task 1

The graphs above give information about computer ownership as a percentage of the population between 2002 and 2010, and by level of education for the years 2002 and 2010.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Write at least 150 words.

What is an overview of the data?

An overview statement will summarise the purpose of the graph(s) in one or two sentences. You can see how this has been done in the question in the task above: The graphs above give information about computer ownership as a percentage of the population between 2002 and 2010, and by level of education for the years 2002 and 2010.

However, you will get no marks for simply repeating the words in the question. You need to put the overview into your own words.

How do I start?

  1. Spend some time looking at the graphs. Look at the labels on the X-axis and the Y-axis. Make sure you really understand the information that is being displayed.
  2. Start the overview statement in the present tense, like this:
    This chart shows…
    The information in the chart illustrates….
    The graph compares…
    The diagram explains…
  3. Follow this with a summary of the purpose of the graph that is clear, complete and concise:
    These graphs show the growth of computer ownership by education level between 2002 and 2010, and compare this with the growth of computer ownership overall for the same period. In both cases ownership is expressed as a percentage of the population as a whole.

Practice exercise 1

Read the four data overview statements below. Then go to this article and match each statement with one of the four graphs in the report. (Answers below.)

    [Could you please check my writing task 1 which was taken from the Road to IELTS, as I am a bit confused about this.]
    Task 1
    The graphs above give information about computer ownership as a percentage of the population between 2002 and 2010, and by the level of education for the years 2002 and 2010.

    The information in the graphs illustrates the percentage of the population and level of education who has the computer ownership since 2002 to 2010.
    Overall, the percentage of computer ownership by the inhabitants around this 8 years were not changed significantly as it was held a dramatic change in education level.
    In education level, the percentage of possessing computer was higher in both 2000 and 2010 by postgraduate qualification (by holding the figures nearly 80% and 90%) than no high school diploma (by holding the figures about 15% and just above 40%). However, it seemed, in the year of 2000 and 2010, in the sector of pedagogy, the higher level of educations have more ownership of the computer. As in the college who were not yet finished owned 55% in 2002 and 80% in 2010. In addition, the proportion of possessing computer by bachelor degree level was 70% in 2002 and almost 90% in 2010. In the level of postgraduate qualification, the proportion was 10% less in 2000 than the year 2010 and the figures were 80% and 90% respectively.
