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 statistic t has the same sign as the correlation coefficient r. The p -value is the combined area in both tails. WebCompare r to the appropriate critical value in the table. If r is not between the positive and negative critical values, then the correlation coefficient is significant. If r is significant, then you may want to use the line for prediction. Suppose you computed r = 0.801 using n = 10 data points. df = n – 2 = 10 – 2 = 8.
