Quizplus · Accepted Answer

For the t test to be considered robust, both a relatively large sample size and approximately equal sample sizes are needed. A larger sample size helps to increase the power of the test, making it less sensitive to violations of the normality assumption. And equal sample sizes help to ensure that the test is not biased towards one group over the other, making it less sensitive to violations of the equal variance assumption.
