Question

If the class intervals are discontinuous, adjustment factor must

be _______ to the class intervals.​

Answer 1

Step-by-step explanation:

Given that: If the class intervals are discontinuous, adjustment factor must be _______ to the class intervals.

To find: Fill up

Solution:

If the class intervals are discontinuous then adjustment factor must be subtracted from lower class limit and added to upper class limit to the class interval.

Extra info: Normally adjustment factor is taken as 0.5.

Thus,0.5 is subtracted from the lower limit and 0.5 is added to upper class limit as well.

For eg: Class interval 5-10 and 11-15 and so on then true class limit for every class can be calculated using adjustment factor

In such case true class interval will be 4.5-10.5 and 10.5 -15.5 and so on.
