Finding the Measures of Variation:
Find the (a) explained variation, (b) unexplained variation, (c) total variation, (d) coefficient of determination, and (e) standard error estimate Se. In each case, there is a significant linear correlation so that it is reasonable to use the regression equation when making predictions.
Blood Pressure Measurement: Fourteen different second-year medical students took blood pressure measurements of the same patient and the results are listed below (data provided by Marc Triola, MD).
