Class 6 Maths Data Handling Bar Graph

Bar Graph

Bar Graph is another method of representing data visually. In the case of bar graph or bar diagram, Bars of uniform width are drawn horizontally or vertically with equal spacing between them and then the length of each bar represents the given number.

The following problems will explain how a bar graph is interpreted:

Problem:  Observe this bar graph which is showing the sale of shirts in a readymade shop from Monday to Saturday.  • What information does the above bar graph give?

The bar graph tells us the number of shirts sold on each day from Monday to Saturday.

• What is the scale chosen on the horizontal line representing number of shirts?

The scale chosen on the horizontal line, that is, x axis is 1 unit length = 5 shirts.

• On which day were the maximum number of shirts sold? How many shirts were sold on that day?

Since Saturday has the longest bar, maximum number of shirts was sold on Saturday. The number of shirts were sold were 60*5 = 300 shirts.

• On which day were the minimum number of shirts sold?

Minimum number of shirts was sold on Tuesday. The number of   shirts  sold were 10*5 = 50 shirts.

• How many shirts were sold on Thursday?

Thursday is represented by a bar of 35 units. Hence the numbers of    shirts sold on this day were 35*5 = 175 shirts.
