A chi-bar-squared distribution is a mixture of chi-square distributions, mixed over their degrees of freedom. You’ll often find them when testing a hypothesis with an inequality. Uses The chi-squared distribution has many uses in statistics, including: Confidence interval estimation for a populat...
