Quizplus · Accepted Answer

The chi-square goodness of fit test is used to determine whether an observed frequency distribution is significantly different from an expected frequency distribution when the variable is categorical with more than two categories. In other words, it is used for multinomial experiments with categorical data. Therefore, option B is the best choice. Options A, C, and D are not correct because they refer to different types of hypothesis tests that use different statistical methods.
