I will show the way.
Step-by-step explanation:
r is the correlation coefficient

To find SSxy
SSxy= ∑
- ∑
To find SSxx
SSxy= ∑
-
∑x
/n
To find SSyy
SSxy= ∑
-
∑y
/n
if your r is near +1, it shows strong positive correlation. Y is proportional to X.
And if it nears -1, it would show strong negative correlation. Y is inversely proportional to X.
