Paired T Test Formula. Please note that a pair of samples each of which are not from normal a distribution often yields differences that are normally distributed. Common applications of the paired sample t test include case control studies or repeated measures designs.
It can be calculated as follow. Where s a and s b are the standard deviation of the the two groups a and b respectively. Where d bar is the mean difference s is the sample variance n is the sample size and t is a student t quantile with n 1 degrees of freedom.
Common applications of the paired sample t test include case control studies or repeated measures designs.
