The mean of the chi-square distribution is its degrees of freedom. The expected variance of the distribution is 2df. If the variance is 2df, the standard deviation must be sqrt(2df). There are tables of chi-square so you can find 5 or 1 percent of the distribution. Chi-square is additive. 2017-06-10 Chi-square tests come in two types: Chi-square test for independence Chi-square goodness of fit test: used to test if the observed data match theoretical or expected results. We will focus on this test.
