To calculate effect size for an independent-samples t test, use:
A) Cohen's d.
B) sample size.
C) z score.
D) standard deviation scores.

Question

Quizplus · Accepted Answer

Cohen's d is the most appropriate choice for calculating effect size for an independent-samples t test. It measures the standardized difference between the means of two groups and provides a common metric for comparing effect sizes across different studies. Sample size, z score, and standard deviation scores may be relevant for other calculations but are not specifically used to calculate effect size for an independent-samples t test.
