WebApr 2, 2024 · The p-value is calculated using a t -distribution with n − 2 degrees of freedom. The formula for the test statistic is t = r√n − 2 √1 − r2. The value of the test statistic, t, is shown in the computer or calculator output along with the p-value. The test statistic t has the same sign as the correlation coefficient r.
