The t-test is most commonly used to compare a single mean with a hypothesized value, two means from paired data, or two means from the unpaired data. Here is the T statistic formula for two samples by which you can calculate the pooled standard deviation, t-statistic and standard error. The Mean, standard deviation and sample size of the two samples are the data's which are necessary for doing the calculations using the given T statistic formula.

Standard Error (S) = R x √(1 / n

T - Statistic = μ
