Use table D for chi square critical value 384. χ2 O-E2 E where O the observed frequency in each category E the expected frequency in each category and the summation is made over all categories. In probability theory and statistics the chi-square distribution also chi-squared or χ2-distribution with k degrees of freedom is the distribution of a sum of the squares of k independent standard normal random variables.
