This is the problem as I received it, I hope that someone can explain how to do it, as I am at a loss
Correlation Coefficient Definition*
x̄)/Sx))∗((yi-ȳ)/Sy))/n-1Computational Formula for r**
1) How do you get from Definition to Computational? Show that * is the same as **
2)* and ** are for samples, show that you get ** for population correlations coefficient.
I would really appreciate any help on this as I am truly lost on how to do this. Thanks
