The rank correlation of their scores is -0.65. Interpret this.

Question

• 两名人力资源专家给单独的分数来在一系列标准的面试人选。他们的成绩的等级相关系数为-0.65。解释这个。

Answer 1

The rank correlation relates the order of one set to the order of an allegedly related set. The negative value indicates that as one increases the other decreases, and vice versa. The magnitude 0.65 indicates a weak correlation. To establish a confidence interval, or to test the null hypothesis, we would need more information: degrees of freedom and set sizes. (It may also help to have the Japanese context translated into English.)
