The aim of this article is to show that the T-test can be misleading. We argue that normal or Student's approximation to the distribution L(tn) of Student's statistic tn does not hold uniformly over the class Pn of samples fX1; :::;Xng from zero-mean unit-variance bounded distributions. We present lower bounds to the corresponding error. We suggest a generalisation of the T-test that allows for variability of possible approximating distributions to L(tn)
