Question

Distinguish between 'exclusive method' and 'inclusive method' of frequency distribution with example.​

Answer 1

• For example, among class intervals 10-20 and 20-30, 20 is included in the next class interval i.e., 20-30 and not in 10-20. Inclusive method: Under this method, upper class limit is included in a class interval. So here, both upper class limit and lower class limit are parts of the class interval.
