The t test is relatively robust, meaning that its assumptions can be violated without changing the rate of Type 1 and Type 2 errors. This does not mean that the t test is valid with ordinal data or that the critical value of t is independent of the number of subjects sampled. Additionally, while the t test can be used with small sample sizes, there is no specific cutoff at 20 subjects in each treatment group.
