good mring
what is mean by exclusive and inclusive classes

Answer 1

Inclusive Class Interval:
When the lower and the upper class limit is included, then it is an inclusive class interval. For example - 220 - 234, 235 - 249 ..... etc. are inclusive type of class intervals. Usually in the case of discrete variate, inclusive type of class intervals are used.

Exclusive Class Interval:
When the lower limit is included, but the ulpper limit is excluded, then it is an exclusive class interval. For example - 150 - 153, 153 - 156.....etc are exclusive type of class intervals. In the class interval 150 - 153, 150 is included but 153 is excluded.
Usually in the case of continuous variate, exclusive type of class intervals are used.
