What needs to be known to determine the critical values for an independent-samples t test?
A) results of the power analysis
B) effect size
C) total degrees of freedom
D) degrees of freedom for the largest group

Question

Quizplus · Accepted Answer

The critical values for an independent-samples t-test are determined by the total degrees of freedom, which is calculated based on the sample sizes of the two groups being compared. This is because the degrees of freedom affect the shape of the t-distribution, which in turn determines the critical t-values for a given significance level.
