Question

Quizplus · Accepted Answer

Variability refers to the differences or spread in numerical scores on a test. Option A is incorrect as the average difference would refer to the central tendency of the scores rather than the differences between them. Option B (statistical significance) is a term used to refer to the probability of finding an observed effect (such as the score differences) given that it is not due to chance, and is not directly related to score variability. Option D (confounding) refers to the presence of an extraneous variable that affects both the independent and dependent variables, and is not applicable in this context.
