REPRESENTATION OF DATA BY A BAR GRAPH

We can represent data by the different lengths/heights of bars to
show/compare the information at a glance.

For example; 1 can for 1 thing/person 2 can for 2 things/person etc.

Example: The following drink of a group of children are the following.

Drink Juice Milk Lemon Cola Tea Coffee

Number of
3 4 6 5 1 2
Children

Draw a bar graph to represent the above data

Solution: We show the drive on the horizontal line (x-axis) and number of
children on the vertical line (Y-axis).

We show 1 unit of height to show 1 child.
