Question

Which of the following notations represents the sample variance?

A. overline{x}
B. s^2
C. mu
D. sigma^2

Answer 1

The sample variance is represented by the notation s^2 (option B).

Step-by-step explanation:

The sample variance is represented by the notation s^2 (option B). The symbol s^2 is used to calculate the variance of a sample, while sigma^2 (option D) represents the population variance. The sample variance is calculated by taking the average of the squares of the deviations. It measures how spread out the data points are in the sample.
