If you have two groups with equal variances,which of the t-tests below would you use?

Question

Quizplus · Accepted Answer

When the variances of both groups are equal, the equal variance t-test (also known as the independent samples t-test) should be used. This test assumes that the samples are independent, normally distributed, and have equal variances. The unequal variance t-test should only be used if the variances are significantly different. The equal means t-test and unequal means t-test are not appropriate in this scenario as they are based on different assumptions about the data.
