A goodness-of-fit test is used to determine whether observed data frequencies match expected data frequencies. It requires nominal or ordinal data, which means that the variable being tested can be classified into distinct categories that do not have a numerical value assigned to them. The assumption of normality (choice A) is not necessary for a goodness-of-fit test. Additionally, population variance (choice C) does not need to be known.
