When the pairs are generated by matching the matching criteria may not be important. In this case, the paired and unpaired tests should give similar results. WebThe formula of the paired t-test is defined as the sum of the differences of each pair divided by the square root of n times the sum of the differences squared minus the sum of the squared differences, overall n-1. The formula for the paired t-test is given by. t = ∑d √ n(∑d2)−(∑d)2 n−1 t = ∑ d n ( ∑ d 2) − ( ∑ d) 2 n − 1.
