Draw a histogram for the following data: Class interval 30 - 40 40 - 50 50 - 60 60 - 70 70 - 80 80 - 90 90 - 100 Frequency 3 7 12 15 8 3 2

The given data is, Class interval 30 - 40 40 - 50 50 - 60 60 - 70 70 - 80 80 - 90 90 - 100 Frequency 3 7 12 15 8 3 2 In the histogram, we represent the groups of observations (i.e., class intervals) on the horizontal axis and the height of the bars shows the frequency of the class interval. Also, there is no gap between the bars as there is no gap between the class intervals. Take the scale as along the horizontal axis, 1 unit = 10 and along the vertical axis, 1 unit = 1 . The jagged line or the broken line is shown along the horizontal axis to show the gap between 0 to 30 .

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

Total number of students = 300 Now, we calculate the central angle for each subject as follows: Subject Number of students Central angle Maths 75 75 300 × 360 ° = 90 ° Science 60 60 300 × 360 ° = 72 ° English 90 90 300 × 360 ° = 108 ° Moral science 40 40 300 × 360 ° = 48 ° Sociel science 35 35 300 × 360 ° = 42 ° After drawing a circle of any radius, we will draw the first sector with angle 90 ° at the centre of the circle. After this, we draw the sectors with angles 72 ° , 108 ° , 48 ° and 42 ° respectively, in the centre and label every sector with the respective subject.

The runs scored by a cricket team in the first 10 overs are given below: Overs I II III IV V VI VII VIII IX X Runs 4 3 6 2 1 4 8 10 6 12 Draw a graph to represent the above data.

Given Overs I II III IV V VI VII VIII IX X Runs 4 3 6 2 1 4 8 10 6 12 Take overs on X - a x i s and runs on Y - a x i s
