Use for a chi-square goodness-of-fit test. First enter the observed frequencies as positive integers in a column of the Sample Editor window. Also enter a second column consisting of either the frequency counts that are expected or the proportions expected for each category.Select Analysis, Goodness-of-Fit.Select the option of “Unequal Expected Frequencies” to test the null hypothesis that the different categories have probabilities that are not all the same. Enter a significance level, such as 0.05. Identify the column containing the observed frequencies. Identify the column containing either the expected frequency counts or the expected proportions. Results include the chi-square “Test Statistic” and the critical value of chi-square, and the P-value. |
