Question

Quizplus · Accepted Answer

The chi-square goodness-of-fit test can be used to test whether a sample follows a specified distribution. It is commonly used to test for normality, as well as other distributions such as the Poisson, binomial, or exponential. It is important to note that this test assumes no open-ended classes and the degrees of freedom can be calculated based on the number of categories being tested.
