Webis distributed as a chi-square random variable with 1 degree of freedom. Proof To prove this theorem, we need to show that the p.d.f. of the random variable \(V\) is the same as the p.d.f. of a chi-square random variable with 1 degree of freedom. WebMay 24, 2024 · The degrees of freedom (df): For chi-square goodness of fit tests, the df is the number of groups minus one. Significance level (α): By convention, the significance level is usually .05. Example: Finding the critical chi-square value Since there are three groups (Garlic Blast, Blueberry Delight, and Minty Munch), there are two degrees of freedom.
