Quizplus · Accepted Answer

Familywise error refers to the likelihood of making at least one type I error when conducting multiple statistical tests on a single set of data. As more comparisons are made within the set, the likelihood of at least one type I error occurring by chance increases, leading to a higher familywise error rate. Therefore, choice A is the best answer.
