Question

. Make frequency distribution of the following series! 1,2,2,3,3,3,3,3, 4, 4, 4, 4, 4, 4,4 4, 4, 5, 5, 5, 5, 5, 5, 5, 6, 6, 6, 6, 7, 7. ​

Answer 1

Answer:

First arrange the data in ascending order

1,2,2,2,2,3,3,4,4,5,5,6,6,7,7,8

The largest number =8

The smallest number =1

Range = largest number − smallest number =8−1=7

We shall calculate an approximate group size, by dividing the range by the number of groups we want.

If we want 3 groups, then Divide range with number of groups =

3

7

=2.333

The class width will be 2, Starting from 1.
