Finding correlations in data
WebOct 20, 2024 · To determine if a correlation coefficient is statistically significant, you can calculate the corresponding t-score and p-value. The formula to calculate the t-score of a correlation coefficient (r) is: t = r * √n-2 / √1-r2 The p-value is calculated as the corresponding two-sided p-value for the t-distribution with n-2 degrees of freedom.
