B) Identify any possible outliers.

C) Determine if the point is influential. To change in slope or intercept is significant if it is larger than 10%.


"The point (is/is not) an influential point because the slopes with the point included and without the point included (are/are not) significantly different, and the intercepts (are/are not) significantly different."

Extracted text: An influential point An outlier may or may not be an influential point. To determine if a point is influential, find the regression lines including all the points in the data set, and excluding the possible influential point. If the slope or y-intercept of the regression line shows significant changes, the point can be considered influential. An influential point can be removed from a data set only if there is proper justification. a point in a data set that can greatly affect a regression line.
