Solution 1 of 2 You were asked to calculate the correlation coefficient, r. Completion Percentage 55.5 57 58 58.5 59 Interception Percentage 5 4 2.5 2 1.5 To find r, you can use the formula, a scientific calculator, or statistical software. To use the formula, we should first determine n, ∑xy, ∑x, ∑y, ∑x2, and ∑y2. Since we have 5 data points, n=5. In this case our x-values are "Completion Percentage" and our y-values are "Interception Percentage", so we calculate...
