Quizplus · Accepted Answer

This equation represents the variance of a sample, where $x_i$ are the individual sample points, $\bar{X}$ is the sample mean, and $n$ is the sample size. The denominator $n-1$ is used instead of $n$ to correct for the bias in the estimation of the population variance from a sample.

The Following Equation ∑i=1n(xi−Xˉ)2n−1\frac{\sum_{i=1}^{n}\left(x_{i}-\bar{X}\right)^{2}}{n-1}n−1∑i=1n​(xi​−Xˉ)2​ , Represent ______
