Question:

(a) There are equivalent formulas that can be used to find the correlation coefficient and the equation of the line of best fit. A formula used in some statistics books to find the correlation coefficient is.

SS(xy) VSS(x)SS(y)

Where

SS(1) Σx Σ(Σ ) 2 η SSy) -Σy? (Σy)2 Σν?- п SSw) -Σxν (Σx) (Σν) Π

Use this formula to find the correlation coefficient of the set of bivariate data given in Example 1.

(b) Compare your answer with the answer obtained in Example 1.
