27 ASIAN INSTITUTE OF COMPUTER STUDIES (AICS) Activity 2: Strength in Pairs Directions. Describe the strength and direction of correlation of the following pairs of variables. Complete the tables below and compute the value of the correlation coefficient (r) using the formula- E ( X - X) ( Y - Y) VE( X - X) = [ ( Y - P)2 1. The following are the ages (X) of babies in months and their heights (Y) in centimeters. Determine if there is a relationship between their ages and heights.
