Answer 1

Draw an ogive for the following data which gives the marks and number of students:

Marks 0−10 10−20 20−30 30−40 40−50

Students 6 21 16 32 10

Easy

ANSWER

To draw the Ogive or cumulative frequency curve, we need to find out the cumulative frequency.

Class interval 0−10 10−20 20−30 30−40 40−50

Frequency 6 21 16 32 10

Cumulative frequency 6 27 43 75 85

Let us take the scale on X-axis as 1 cm=10 and Y-axis as 1 cm=10 and mark the cumulative frequency against the upper limit of each class interval. Joining these points by a smooth curve, we get ogive or cumulative frequency curve. The curve looks like this.
