WebOct 14, 2015 · I can understand the need for the $\chi^2$ test; this is not the testing of hypothesis concerning means and variances. I am clear at defining df for $\chi^2$ for testing variances and test of independence. Specifically, I require the df for verifying whether the given sample set follows the claimed distribution -- the Goodness of Fit test ...
