WebT = t-statistic; m = mean of the group = theoretical mean value of the population; s = standard deviation of the group; n = sample size #2 – Independent Two-Sample T-Test. … WebT.TEST uses the data in array1 and array2 to compute a non-negative t-statistic. If tails=1, T.TEST returns the probability of a higher value of the t-statistic under the assumption that array1 and array2 are samples from populations with the same mean. The value returned by T.TEST when tails=2 is double that returned when tails=1 and ...
