Question

The number of classes a frequency distribution should have is:

• A. Large number
• B. Small number
• C. Neither very small nor very large
• D. None of the above

Answer 1

The correct option is C Neither very small nor very large

Each entry in a frequency distribution table contains the frequency of values within a particular interval. This way, the table summarises the distribution of values in the sample. A large number or a small number of classes might not reveal the basic shape of the data set, and might make it difficult to interpret the given distribution.
