2006-05-17В В· Authors are unaware that Student's t-test is unreliable when variances differ between underlying populations.. Authors are aware of this but consider their samples to have similar variances. Authors believe than the MannвЂ“Whitney U test can effectively substitute for Student's t-test when variances are unequal.. Because the t distribution tends to the normal distribution for large sample If the sample sizes in the two groups being compared are equal, Student's original t-test is highly robust to the presence of unequal variances. Welch's t -test is insensitive to equality of the variances regardless of whether the sample sizes are similar.

The usefulness of the unequal variance t test. To interpret any P value, it is essential that the null hypothesis be carefully defined. For the unequal variance t test, the null hypothesis is that the two population means are the same but the two population variances may differ.
