Exploring the Goodness of Fit in Linear Models - Outlier Data Point at Mid-range: Outlier II Tab

Author(s): 
Scott A. Sinex

The Outlier II tab is a repeat of the Outlier worksheet, except that the scatter is introduced to a mid-range datum point. Vary the scatter of the datum point shown in red on the graph. How does the scatter influence the regression line? Here the effect is, for the most part, on the intercept until large scatter occurs.
