3. 5. Problem Set: Chapter 14 Correlation and Regression Based on your scatter diagram, you would expect the correlation to be The mean X Score is Mx and the mean y score is My Now, using the values for the means that you just calculated, fill out the following table by calculating the deyiations from the means for X and Y, the squares of the deviations, and the products of the deviations. 因 Scores Deviations Squared Deviations Products X Y X-Mx Y- My (X - Mx)2 (Y - My)2 (X- Mx)(Y- My) 2 4. 3. 4. 2. The sum of squares for x is SS The sum of squares for y is SS, The sum of products is SP: Because the sign of the sum of products is , the sign of the correlation coefficient The correlation coefficient is r = Look at your scatter diagram again.
