Guide: (Formula for correlation)
PEARSON PRODUCT MOMENT CORRELATION COEFFICIENT formula
n(Exy) - (Ex) (Zy) = In(Ex?) - (Ex)"In(Ey?) - (Ey)"] Where: = mummber of paired values Ex = sum of x values Zy - sum of y values Exy = sum of the products of paired values x and y Ex2 = sum of squared x-values Ey ston of squared y-values6Ed2 p = 1- n(n2 - 1) Where: - difference in the ranks of each pair - number of pairy being correlatedACTIVITY 1: SOLVING WORD-PROBLEMS 1.
