WebJul 1, 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. WebApr 20, 2016 · The measure of correlation is by definition: ρ = P(A ∩ B) − P(A) P(B) √ P(A) (1 − P(A)) P(B) (1 − P(B)) = (P(A ∣ B) − P(A)) P(B) √ P(A) (1 − P(A)) P(B) (1 − P(B)) Now, …
