Answer 1

Hi ,

It is given that ,

Class mid points in a frequency

distribution of age of a group of a person

are 25 , 32 , 39 , 46 , 53 and 60.

size of class intervel = difference between

two consecutive mid values

h = 32 - 25

h = 7

Therefore ,

class size = h = 7

I hope this helps you.

Answer 2

Given Distribution of age of a group of persons are 25,32,39,46,53 and 60.

We know that size of the class interval = Difference between the mid values of consecutive numbers

= > 32 - 25 (or) 39 - 32 (or) 46 - 39

= > 7.

Therefore, the size of the class interval is 7.

Hope this helps!
