Quizplus · Accepted Answer

A goodness-of-fit test is used to determine whether sample data could have been drawn from a population having a specified probability distribution. This test compares the observed frequencies of a particular variable with the expected frequencies based on the specified distribution. A commonly used goodness-of-fit test is the chi-square test. Options A and B are tests of association between variables, Option C is a test for estimating population variance and Option E is a test for estimating population mean.
