Choose the correct option (s):

a) Inclusive class interval is same as discreate class interval

b) Exclusive class interval is same as discreate class interval

c) Inclusive class interval is same as continous class interval

d) Exclusive class interval is same as continous class interval

The correct option is C (a) and (d)
Class intervals like '1 - 10', '11 - 20',.... are called inclusive class intervals because both upper and lower limit belong to that particular class interval

In '1 - 10', 1 and 10 both belong to '1- 10' class interval.

The Inclusive class interval is the same as the discrete class interval.

Class intervals like '1 - 10', '10 - 20',.... are called exclusive class intervals because only lower limit belong to that particular class interval

In '1 - 10', only 1 belong to '1- 10' class interval.

The exclusive class interval is the same as the continuous class interval.
