Question

when calculating the sample standard deviation, what is the divisor in the formula? n+1 n-1 n-2 n

Explanation:

Step1: Recall sample std - dev formula

The formula for sample standard deviation $s=\sqrt{\frac{\sum_{i = 1}^{n}(x_{i}-\bar{x})^{2}}{n - 1}}$, where $n$ is the sample size.

Answer:

B. $n - 1$
