When Pearson’s correlation coefficient is used as an inferential statistic (to test whether the relationship is significant), r is reported alongside its degrees of freedom and p value. The degrees of freedom are reported in parentheses beside r.
WebMar 1, 2024 · As a result, the degree of freedom for a one-sample t-test is n – 1. The DF specifies the form of the t-distribution used by your t-test to get the p-value. The graph below depicts the t-distribution for various degrees of freedom. Because the degrees of freedom are closely tied to sample size, the influence of sample size may be seen.
