Answer:
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.
