Goodness of fit values

WebDegrees of freedom for a chi-square goodness-of-fit test are equal to the number of groups minus 1. The distribution plot below compares the chi-square distributions with 2, 4, and 6 degrees of freedom. To find the p-value we find the area under the chi-square distribution to the right of our test statistic. A chi-square test is always right ...
