The expected frequency within a cell in a contingency table for a chi-square test of independence is determined by.
A)multiplying the marginals for the cell and dividing by N
B)multiplying the marginals for the cell and dividing by the frequency in the cell
C)summing the marginals for the cell and dividing by N
D)summing the marginals for the cell and dividing by the frequency in the cell

Question

Quizplus · Accepted Answer

The expected frequency in a cell for a chi-square test of independence is calculated by multiplying the row total for that cell by the column total, and then dividing by the total number of observations (N). This method ensures that the expected frequencies are based on the marginal totals of the table, providing a basis for comparison with the observed frequencies.
