Bar Graph is the pictorial representation of grouped data, in the form of vertical or horizontal rectangular bars, where the length of bars is proportional to the measure of data.

Step-2. Analyze the data.

Given data of favorite instrument:

Instrument	Number of students
Drums	8
Guitar	12
Piano	5
Trumpet	7

Step1: Draw a horizontal axis and a vertical axis. Label the horizontal axis as “instruments” and the vertical axis as “number of students”. Add the title as Favourite instruments
