Question

Quizplus · Accepted Answer

Effect sizes are standardized scores that allow for comparisons across different studies, as they provide information about the magnitude of the difference between groups or conditions, rather than just indicating statistical significance. This makes it easier to compare the results of different studies and meta-analyses. Option A is incorrect because effect sizes do not indicate all parameters of a group of scores. Option B is incorrect because effect sizes are not a direct indication of statistical significance, although they may be used in conjunction with significance tests. Option C is partially correct, but incomplete, since effect sizes do permit meta-studies, but they do not provide the same information as statistical significance.
