3.15.C—Interpret the p-value for the chi-square test for homogeneity or independence

Interpret the p-value for the chi-square test for homogeneity or independence.

• The p-value is the probability of obtaining a test statistic as extreme or more extreme than the test statistic that was observed (i.e., in the direction of the alternative hypothesis) given that the null hypothesis is true. An interpretation of the p-value for the chi-square test for homogeneity or independence should include a statement that the p-value is computed by assuming the null hypothesis is true in context.
