C)frequency expected
D)both B and C

Question

Quizplus · Accepted Answer

The frequencies observed and expected are recorded using both a chi-square goodness-of-fit test and a chi-square test for independence. The chi-square goodness-of-fit test compares the observed frequencies to the expected frequencies to see if they are significantly different. The chi-square test for independence compares the observed frequencies of two variables to determine if they are independent or if there is a relationship between them. Both tests use the chi-square distribution to determine the significance of the results.
