Effect size is an important tool for making sense of research results because:
A)it tells us the degree to which a result is statistically significant
B)it tells us the magnitude of the statistical effect
C)it limits variance and thus increases power
D)it is always smaller than the variance

Question

Quizplus · Accepted Answer

Effect size tells us the magnitude of the statistical effect, which is important for understanding the practical significance of the results. The degree of statistical significance (A) is important but does not tell us about the magnitude of the effect. Effect size does not limit variance or increase power (C) and it is not always smaller than the variance (D).
