When the Sample Size N Is Greater Than 30, the Spearman

Short Answer

When the sample size n is greater than 30, the Spearman rank correlation coefficient $r _ { s }$ is approximately normally distributed with: $\begin{array}{|l|l|}\hline\text { A. } & \text { mean 0 and standard deviation 1 .}\\\hline \text { B. } & \text { mean 1 and standard deviation \( \sqrt{n-1} \).} \\\hline \text { C. } &\text {mean 1 and standard deviation \( 1 / \sqrt{n-1} \). }\\\hline \text { D. } &\text {mean 0 and standard deviation \( 1 / \sqrt{n-1} \). }\\\hline\end{array}$
