Regression analysis measures the average amount of change in the outcome variable, whereas high-low analysis only focuses on the extreme values (high and low) of the outcome variable. Regression analysis also takes into account all observations, not just the extremes. Regression analysis does not necessarily ignore non-representative data, but efforts are made to identify and address outliers and influential observations.
