Task 3: Understand the main points of
information presented in charts
Now, we will focus on exploring charts. This type
of GOs is also popular to students and teachers. Therefore, it is necessary for
you, as professional EFL teachers, to understand about how to comprehend and
present information in charts.
What are
tables? What is the purpose of presenting information in tables? How to read
tables? How are information presented using them?
First,
watch these short videos. It provides you with information about what charts
are.

Bar Charts[3]
You
can display information in the form of a bar chart. Bar charts show data in a
visual and easy to read way.
Below are the results of the survey of ‘Pets owned by people in Tregain
Street’ shown as a bar chart:
A bar chart can be used to compare figures. Below is a bar chart with two
bars or columns for each category (type of pet). This type of bar chart is
known as a dual bar chart. The key
on the right-hand side of the bar chart shows that the blue (shaded) bars
represent the men’s answers and the red (lined) bars show the women’s answers.
Key points
A bar chart needs a title. The
title tells you what the bar chart is about. In this example the title is
‘Survey of pets owned by people in Tregain Street’.
The horizontal axis is the line
which goes along the bottom of the chart. It should have a label. Here the
horizontal axis is labelled ‘Types of pet’. Each of the bars should also be
named, for example here they are labelled ‘dog’, ‘cat’ etc.
The vertical axis is the line
which goes up the left-hand side of the chart. It too should be labelled, in
this case the label is ‘Number of pets’.
Reading bar charts
To read the bar chart below you need to look at the scale on the vertical
axis and then read across to the top of each bar.
In this bar chart each bar is labelled, and you can read that:
¾
12 people owned dogs
¾
6 people owned cats
¾
7 people owned hamsters
¾
4 people owned rabbits
¾
1 person owned other type of pets
If your bar chart does not have lines like those in the above example, then
you may need to use a ruler to help you read across to the scale.
Did you notice the marks on the scale? The difference between each mark on
the scale is 2, so we say the scale goes up in divisions of 2. Can you see that the ‘hamster’ bar is half way
between divisions? So, the number of people who own hamsters is halfway between
6 and 8, which is 7. Sometimes bar charts can be shown with horizontal bars. In
this case, you will need to check the length and not the height of the bars to
read the scale. For example:
