c) In the formula we see the following quantities: x, x, sx, y, y, sy, n 1 For our sample of 5 cereals, which of these quantities will be xed in the formula [calculated once and then used as a constant) and which will have different values for the different cereals? d) If we calculated r by hand for our sample of 5 cereals, how many terms will we add together [before we divide by n 1]? Learning Objective: Relate the formula for r to the distance of data points from the mean lines. Here we have sugar content per serving and Consumer Report ratings for 5 cereals. Sugar Consumer 80 (gms per Report serving) Rating 60 0 65 CR_rating 50 00 45 40 50 30 20 2 4 6 8 10 sugar The data has a linear form, so we can use the correlation coefficient to describe the oftha association. Based on the scatterplot give an estimate for the
