7. The t tests The BMJ

Use tables of the t-distribution to compare your value for T to the t n 1+n 2−2 distrib-ution. This will give the p-value for the unpaired t-test. NOTE: For the unpaired t-test to be valid the two samples should be roughly normally distributed and should have approximately equal variances. If the variances are obviously unequal we must use: SE(¯x 1 −x¯ 2) = r s 2 n1 1 + s 2 n 2 Then: ¯x
