1, Exercise 1o:
**

SS Predicted is the sum of the squared deviations of
predicted scores from the mean. If the regression model is not at all useful,
then the predicted score will be the mean for each case, and SS Predicted will
be zero. If the regression model is only slightly helpful, then the predicted
scores will be only slightly different from the mean, and SS Predicted will be
small relative to SS Total. This plot would show virtually no linear
relationship between X and Y, and the regression line would be close to the
horizontal line for the mean of Y.
