Question

For a chi-square test of independence, the _______ must equal the ______.

Row totals ; column totals

Total of the expected frequencies ; total for the observed frequencies

Expected frequencies for any row ; expected frequencies for every other row

Sum of the observed frequencies ; sample size

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
