The sampling distribution of the $\frac { ( n - 1 ) s ^ { 2 } } { \sigma ^ { 2 } }$ quantity follows a Chi-square ($\chi^2$) distribution. This formula is used in statistics to estimate the variance of a population based on a sample variance, where $s^2$ is the sample variance, $\sigma^2$ is the population variance, and $n$ is the sample size.
