Question

In which of the following frequency distributions, the class intervals overlap?

• A. Discrete frequency distribution
• B. Discontinuous frequency distribution
• C. Both, Continuous frequency distribution as well as Discontinuous frequency distribution
• D. Continuous frequency distribution

Answer 1

The correct option is D

Continuous frequency distribution

Overlapping class intervals are nothing but continuous class intervals, where, by convention, the upper limit is excluded from the class interval. So, these class intervals are formed in continuous frequency distribution.
