WebSep 22, 2011 · For the chi-square goodness of fit, the data is divided into k bins and the test statistic is defined as \( \chi^{2} = \sum_{i=1}^{k}(O_{i} - E_{i})^{2}/E_{i} \) ... of fit y ** ***** Anderson-Darling Goodness of Fit Test (Critical Values from Published Tables) Response Variable: Y H0: The distribution fits the data Ha: The distribution does ... WebThe degrees of freedom is calculated as df = k-1, where k is the number of categories. In this case, k = 4, so df = 3. Using alpha = 0.05, the critical value of chi-square with 3 degrees of freedom is 7.815. e. Since the calculated X^2 statistic (4.09) is less than the critical value of chi-square (7.815), we fail to reject the null hypothesis.
