Finding linear correlation coefficient r

WebApr 2, 2024 · r = sample correlation coefficient (known; calculated from sample data) The hypothesis test lets us decide whether the value of the population correlation coefficient ρ is "close to zero" or "significantly different from zero". We decide this based on the sample correlation coefficient r and the sample size n. WebThe formula for the test statistic is. t = r n − 2 1 − r 2. t = r n − 2 1 − r 2. The value of the test statistic, t, is shown in the computer or calculator output along with the p -value. The test …
