X-Y

2-6

4-9

6- 3

8- 12

10- 15

When using pearson correlation it will be straight forward, however, when using spearman, should we arrange the data before running the test? Something like

X- Order X ** Y - Order Y

2-1 ** 6

4-2 ** 9

6- 3 ** 3

8- 4 ** 12

10- 5 ** 15

then we order according to Y

X- Order X ** Y - Order Y

6- 3 ** 3 - 1

2-1 ** 6 - 2

4-2 ** 9-3

8- 4 ** 12 - 4

10- 5 ** 15 - 5

Then we compare the ranks

Order X ** Order Y

3 ** 1

1 ** 2

2 ** 3

4 ** 4

5 ** 5
