The estimated population variance is represented by.
A)s
B) $s ^ { 2 }$
C) $\sigma ^ { 2 }$
D) $\sigma$

Question

Quizplus · Accepted Answer

The estimated population variance is typically represented by s squared, which is denoted as s². This is because the sample variance is an estimate of the population variance, and we use the notation s² to represent the sample variance. The population variance is denoted by σ², but since we don't usually know the actual population variance, we use the sample variance as an estimate. Therefore, the best choice is B.

The Estimated Population Variance Is Represented By s2s ^ { 2 }s2
