T Test Formula. If tails is any value other than 1 or 2 t test returns the num. What is independent.
T test statistic value can be computed as given. If there is any considerable difference between the two pairs of samples then the mean of d is anticipated to be far from 0. If tails or type is nonnumeric t test returns the value.

If tails is any value other than 1 or 2 t test returns the num. In this formula t is the t value x 1 and x 2 are the means of the two groups being compared s 2 is the pooled standard error of the two groups and n 1 and n 2 are the number of observations in each of the groups. The student s t test is shown below. If array1 and array2 have a different number of data points and type 1 paired t test returns the n a error value.
