WebThe chi-square test tests the null hypothesis that the categorical data has the given frequencies. Observed frequencies in each category. Expected frequencies in each category. By default the categories are assumed to be equally likely. “Delta degrees of freedom”: adjustment to the degrees of freedom for the p-value. A chi-squared test (also chi-square or χ test) is a statistical hypothesis test used in the analysis of contingency tables when the sample sizes are large.
