WebStudent's t -test assumes that the sample means being compared for two populations are normally distributed, and that the populations have equal variances. Welch's t -test is designed for unequal population variances, but the assumption of normality is maintained. [1] Welch's t -test is an approximate solution to the Behrens–Fisher problem .
