What do we use to calculate the expected cell frequencies when applying chi-square to a data table to test independence?
A) Marginal totals
B) Binomial distribution
C) Experimental sampling distribution of chi-squared
D) Normal distribution

Question

Quizplus · Accepted Answer

We use the marginal totals to calculate the expected cell frequencies in a chi-square test of independence. This is done by taking the row total, multiplying it by the column total, and dividing by the grand total to obtain the expected frequency for each cell. The binomial distribution, experimental sampling distribution of chi-squared, and normal distribution are not used to calculate expected cell frequencies in a chi-square test of independence.
