Mean 1 and mean 2 the average values of each of the sample sets s diff the standard deviation of the differences of the paired data values n. Mathematically it is represented as t x 1 x 2 s21 n 1 s22 n 2. Student t test is a statistical test which is widely used to compare the mean of two groups of. There are two types of tails are there.
