Bar Graphs

A bar graph is another way of represen ng the collected data by drawing bars of diff erent
heights. It consists of a ver cal line and a horizontal line that meet at a certain point
marked 0 (zero). We usually draw a bar graph by selec ng an appropriate scale. Bars are
drawn by keeping equal space between them.

Just like a pictograph, a bar graph helps us to compare the given data or informa on. It
can be represented both horizontally and ver cally.
