Question

In a group, frequency data class interval are 0-20, 20-40, 40-60 ...... then find the class width​

Answer 1

Answer:

20

Step-by-step explanation:

Class width or class size means the the difference between the upper boundary and lower boundary

⇒ class width = 20 -  0 = 20

Answer 2

Given:

In a group, frequency data class interval are 0-20, 20-40, 40-60 . . .

To Find:

Class width​

Solution:

We know that,

Class width or class size refers to the difference between the upper boundary and lower boundary.

So,

Here we have

Upper Limit = 20

Lower Limit = 0

This implies that, Class width = 20 - 0 = 20

Hence, in frequency data, class intervals are 0-20, 20-40, 40-60 . . .  , the class width is 20.
