The Student T test formula is used to compare the means of two groups. It is a parametric test, which means it assumes that the data is normally distributed. The formula involves calculating the standard error of the difference between the means, which can be expressed as:

The result of the calculation is a T-score, which indicates whether the difference between the means is statistically significant.
