4. Scatter plots and calculating correlation Suppose you are given the following five pairs of scores: XY61926384110Create a scatter plot of these scores in the following diagram. For each of the five (X,Y) pairs, 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. Based on your scatter plot, you would expect the correlation to be _______ .The mean X score is Mx = _______ , and...
