Read the following statements about frequency distribution: 1. Exclusive class intervals ensure continuity. 2. Inclusive class intervals leave no gaps. 3. Sturges' rule helps determine the number of classes. Which statement(s) is/are correct?

A. 2 and 3 only

B. 1, 2 and 3

C. 1 and 3 only

D. 1 and 2 only

Answer: Option C

Solution (By JKExamLibrary)

Exclusive intervals (e.g., 0-10, 10-20) are continuous; inclusive intervals (0-9, 10-19) have gaps. Sturges' rule gives k = 1 + 3.322 log N. Statement 2 is wrong because inclusive intervals do have gaps.
