问题如下：
Calculate the rank correlations for the following data:
选项：
A.-0.50
B.0.25
C.0.72
D.0.81
解释：
The first step is to complete the table by calculating the ranks of each observation (Rxi and Ryi) within its individual series and then calculate the difference between the ranks for each observation i:
我不把X和Y从小到大列出来也不知道他们每个的顺序，不能遇到一个数一次对吧？然后我排完大小还得对照着表格再写一遍大小的顺序，然后再平方加总，再套公式，一套下来最快也要5分多钟。这种题目考试的时候有没有快速一点的解题方式？
