WebUsing the T.TEST Formula to Find the p-Value in Excel. A t-test is a statistic that can be used to determine if there is a significant difference between the means of two groups. The T.TEST formula in Excel is used to perform a t-test and return the probability of a significant difference between two datasets, in other words, the p-value. Web27 jun. 2015 · If T is a random variable with that distribution then the P-value p is P ( T > t). That is, 1 − p = P ( T ≤ t). The value t you wish to reclaim from the reported p is then the inverse CDF (quantile) function of 1 − p . For example, if n = 16, and p = 0.037, then we could use statistical software to obtain t = 1.92.
