B) the observed frequency must be at least five for each category
C) the expected frequency must be at least five for each category
D) the expected frequency must be at least ten for each category

Question

Quizplus · Accepted Answer

The requirement in conducting a goodness-of-fit test is that the expected frequency must be at least five for each category. This ensures that the chi-square distribution used in the test is appropriate and reliable. Some sources may also suggest a minimum expected frequency of 10 for each category, but the more common threshold is five. The observed frequency does not have a specific minimum requirement, but it is recommended to have a sufficiently large sample size to ensure accuracy and reliability of the test results.
