The equation depict what happens when a constant value is subtracted from one of the variables.

twenty points lower. The correlation doe not change because the fundamentals of the equation
(xi - ) does not change. Validity is reduced because all values are 20 points away from the true
value (which will show in an intercept b = -20)
When evaluating a measure for validity one has to look at what? - with Answers:At the
correlation, slope, and intercept because each addresses a different aspect of the total error
