The Student's t-statistic is used to test the null hypothesis that the rank correlation coefficient (such as Spearman's rank correlation coefficient) is zero. This involves converting the correlation coefficient to a t-score and then comparing this score to a critical value from the t-distribution to determine statistical significance.
