Test T Formula. T score intercept α β t score slope s x 2 x 2. The one sample t test formula is used to compare the mean of one sample to a known standard mean.
Firstly determine the observed sample mean and the theoretical population means specified. T test uses means and standard deviations of two samples to make a comparison. In this formula t is the t value x1 and x2 are the means of the two groups being compared s2 is the pooled standard error of the two groups and n1 and n2 are the number of observations in each of the groups.

The exact formula depends on the t test type check the sections dedicated to each particular test for more details. Examples of t test formula with excel template.
