The following table shows the subjects preferred by 300 students of a school during a survey. Represent it by a pie chart. Subjects Maths Science English Moral Science Social Science Total Number of students 75 60 90 40 35 300

Now, for pie chart, we have to find the angle made by each subject at the centre. For maths, angle at centre is, ⇒ 75 300 × 360 º = 1 4 × 360 = 90 º Science, angle at center is ⇒ 60 300 × 360 º = 1 5 × 360 º = 72 º for english, angle at center is ⇒ 90 300 × 360 º = 3 10 × 360 º = 3 × 36 = 108 º for social science, angle at center is ⇒ 35 300 × 360 º = 7 6 × 36 º = 7 × 6 = 42 º for Moral science ⇒ 40 300 × 360 º = 4 3 × 36 º = 4 × 12 = 48 º Hence pie chart

Draw a histogram to represent the following data of the heights of 60 boys of a school. Height (in cm ) 125 - 130 130 - 135 135 - 140 140 - 145 145 - 150 Number of boys 12 14 18 10 6

A histogram is the graphical representation of data where data is grouped into continuous number ranges and each range corresponds to a vertical bar. Taller bars show that more data falls in that range. Given table: Height (in cm) 125 - 130 130 - 135 135 - 140 140 - 145 145 - 150 No. of boys 12 14 18 10 6
