Unformatted text preview: This is using the regression line to predict scores based on this relationship. Our measure of variability or accuracy in this prediction is our standard error of the estimate, which is 26.64945. How much smaller is this value than your original estimate of variability? 31.56711 26.64945 = 4.91766 What percentage of your original variability estimate is this difference between estimates? What is this number (conceptually) HINT look back earlier in the lab... what number is this very close to? 4.91766/31.56711= .1558 .... Around 16%.... PIP!
