Introduction to Graphs

(1)Graph is a diagram to show relationship of two or more variables.

(2)Types of Graphs

(a) Bar Graphs

A bar graph is a representation of numbers using bars of uniform width. The length of the bars shows frequency.

Steps to draw bar graph:

Step 1

Show frequencies on the y axis. Choose a proper scale starting from zero. End the scale at a value greater than the highest value of given frequencies. Show these frequencies on the Y axis using equal divisions.
