Solution

Step 1: Make the required cumulative frequency table for less than curve:

At first, we have to prepare a cumulative frequency table for less than ogive:

Marks GroupNo. of studentsMarksLess than c.f.

0-10

5

Less than 10

5

10-20

8

Less than 20

13

20-30

10

Less than 30

23

30-40

9

Less than 40

32

40-50

6

Less than 50

38

50-60

7

Less than 60

45

Step 2: Draw the ogive:

We plot the cumulative frequencies 5,13,23,32,38, and 45 against the upper limits of the corresponding classes 10,20,30,40,50, and 60respectively.

The smooth curve obtained on joining these points is called less than ogive.


Final Answer:

Finally, we drew the ogive by using data values of marks and the number of students.
