A) use theoretical frequencies
B) add marginal totals to each other and divide by N
C) subtract marginal totals from each other and divide by N
D) multiply marginal totals by each other and divide by N.

Question

Quizplus · Accepted Answer

To find expected frequencies in a test of independence, you multiply the marginal totals (the totals for each row and column) by each other and then divide by the total number of observations (N). This method is used in chi-square tests for independence to determine what the frequency of observations would be if the variables were independent.
