Understanding Graphs – 2

We already have talked about dynamic graphs and how to write an overview for the dynamic graphs. Now, let us have a look at the other kind of graph i.e. the static graph.

Static graph is a graph in which the data is provided for a fixed point of time.

Let us understand how they are answered with the help of the following example.

 

Deaths In SomeLand

Deaths In Someland

The following graph shows data from just one point in time. We can therefore not talk about general trends over time. Here, the major concern is over comparing data between the various sources. Here, we will be comparing the different diseases.

Now, let us first understand this graph. What are the things that you can understand by simply seeing this graph.

First, TB crosses the mark of 1.5 and hence causing the major deaths. The next major disease is diarrhea while Leprosy and AIDS cause the least number of deaths.

Now, let us try to write an overview of the graph –

The graph compares the deaths caused by six diseases in Someland with TB causing the major deaths while Leprosy effecting the least number of people. Apart from TB and Leprosy, the number of deaths are almost same for all other disease.

When we look at static graphs we should be looking for:

  • What are the highest/lowest values?
  • What are the most noticeable differences?
  • Any similarities?
  • Any significant exceptions?

What else to take into consideration?

Try making complex sentences by using sub ordinate clauses.  Complex sentences are sentences with more than one clause and they help increase our marks in the grammatical range part of the marking criteria. You can make sub ordinate clauses by using words such as ‘while’. ‘although’, ‘with’, ‘even though’, ‘whereas’ or ‘and’.

Understanding Graphs – 1

To explain graph properly, it is very important to understand the different types of graphs that come in IELTS. I know you must have heard of pie chart, line graph, tables, but let us have a look at the graphs from a new perspective.

  1. Static Graphs
  2. Dynamic Graphs

Static Graphs – These are the graphs that show data over a certain period of time.

Dynamic Graphs- These are the graphs that show data over a period of time.

Let us have a look at each type of the graph.

Dynamic Graphs –

The graph below shows the percentage of Ontario adults, exceeding cancer prevention recommendations for alcohol consumption, from 2003 to 2012.

Summarize the information by selecting and reporting the main features, and make comparisons where relative.

Write at least 150 words.

Percentage Of Adults

Percentage Of Adults

As you can see, the graph is dynamic because it shows data over a period of time. We should therefore look at the general trend over the time period.

First we need to look at what happened to both the lines from the start to the end. We can see that the green line decreased a bit, while the orange line increased little. Now, let us have a look at both the lines separately. The green line increases till 2005 and then decreases till 2009, finally lowering at 2012.The orange line increases till 2007, decreases till 2009 and then increases till 2012.

These are the most striking or most obvious things we can see when first looking at the graph and these are perfect for our overview.

Let’s put this information into a sentence:

Over the entire period of time, number of males and females, exceeding cancer prevention, showed opposite trends. Females saw a steady increase till 2007 before declining till 2009 and then marking an overall increase. While, percentage of males rocketed, reaching highest point in 2005, before ending up at a decrease in 2012.

When we are looking at dynamic graphs we should be looking out for:

  • What does the data do from the start to the finish?
  • Do they generally go up or down or do they fluctuate?
  • Any significant difference from the general trend?
  • Overall increase/decrease?
  • Peaks/lows?

How To Write An Overview

Overview is the most important part of the writing task 1 of IELTS. The examiner tends to read the overview of the answer first, before reading your other part of the answer. It is therefore very important for you to answer it properly. You need to write it in a way that the examiner gets a clear view of the main trends of the graph,and the other important information that can be grasped from the graph.

What Are You Expected To Write?

Now, if you want a

Band 5 – Relate details mechanically with no clear overview; there  may be no data to support the description

Band 6- Present the overview with information appropriately selected

Band 7- Present the overview clearly telling the main trends, differences and similarities.

What Is An Overview?

Overview is the paragraph that contains  a short summary of the main features. This is done by picking out the 3-4 most significant trends that you notice and then writing them plainly. You need not to either support or go against it. All you are required to do is tell them plainly in the paragraph.

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

This is the sentence you will see after the main question in almost every writing task 1 of the IELTS and this is exactly what you need to do in the overview paragraph.

Let us take an example.

cumulative_emissions of GHG

cumulative_emissions of GHG

Overall there are 10 regions. United States, China, European Union, Russian Federation, Brazil, Indonesia, India, Japan, Canad, Mexico and the rest of the world.Out of these, United States, Japan and European Union and the rest of the world make up the majority, with the rest of the world being the largest. Mexico and Canada  make up a very small proportion.

We can then include these things in an overview paragraph:

The pie chart is comprised of ten regions in total with United States, Japan and European Union contributing maximum to the green house emission. United States has the single biggest share and Mexico, Canada cause the least green house gas emission.

Now, here have I talked about any numbers, who is greater than the other by how much. In this paragraph i.e. the over view paragraph all that I have done is reported what I saw visually and that is exactly what you need to do in the overview paragraph.

CO2 Emission # Line Graph

The graph shows the decomposing carbon dioxide emission trends and its drivers, in east Asia and pacific, 1992-2010.
Summarize the information by selecting and reporting the main features and make comparisons where relevant.
Write at least 150 words.

CO2 Emission

CO2 Emission


The graph represents the ejaculation of carbon dioxide ,in East Asia and Pacific, over a period of 18 years, and the factors responsible for the gas emission; CO2 emissions, carbon intensity of GDP, GDP per capita and population.

Between 1992 and 2010, factors affecting CO2 ejection changed to some extent but the most marked change was in GDP per capita. At the beginning of period the effect of GDP per capita was similar to other factors, however, by 2010, it almost quadrupled, rising from a mark of 1 to 4. The other factor which showed similar trend was carbon dioxide emission. The effect of the emanation of CO2 rapidly increased from 1992 to 1996, when it first showed a decline for the next four years. After 2002, a steady increase has been observed, resulting in a significant increase of three times, over the period of 18 years.

In two categories, carbon intensity of GDP and population, the repercussions on CO2 almost halved, declining from a mark of 1 to nearly 0.5 in both cases. Thus, by the end of the period, the highest increase was marked in GDP per capita ,and the lowest on population.

Overall, the graph shows that a dramatic change took place in factors affecting the CO2 emissions over the period of 1992 to 2010, the part of GDP per capita showing the most marked change.
