problem #4

9 10 8 7 XMONG Create a scatter diagram of these scores in the following diagram. For each of the five (X, Y) pai click on the plotting symbol (the black X) in the upper right corner of the tool, and drag it to the appropriate location on the grid. 6 4 X Y 1 2 3 4 10 10 5 3 MONG 2 1 3 4 6 2 0 € 0 Scores The mean x score is Mx = 3 1 1 4 2 3 6 3 4 Based on your scatter diagram, you would expect the correlation to be Deviations Y X - MX Y - MY 2 4 5 10 10 6 Now, using the values for the means that you just calculated, fill out the following table by calculating the deviations from the means for X and Y, the squares of the deviations, and the products of the deviations. 7 8 9 I 10 and the mean y score is My = Squared Deviations (X - MX)² (Y - My)² Products (X-MX) (Y - MY) 000

The sum of squares for x is SSx of products is SP = = Because the sign of the sum of products is The correlation coefficient is r = The sum of squares for y is SSy = . The sum , the sign of the correlation coefficient Look at your scatter diagram again. If you excluded the point (10, 10), you would expect the recalculated correlation coefficient to be , because
