Question

A data set has n=10 pairs of X and Y values. This data has SSx=10, SSy= 20 and SP=10. Compute the Pearson correlation and explain
r=sp/√ssx ssy =

10/√10*20=
10/√200
Simplify 200 under radical= 200 as 10^2⋅2. √(〖10〗^2 )×2= 10/10√2 or decimal form 14.14213562
Therefore, 10/10√2is the final answer
