    Question

    Suppose we have a scatterplot of variable X and variable Y. The scatterplot contains an outlier. The outlier greatly affects the slope of the regression line, in other words, the regression line changes when the outlier is removed. Choose the best answer.


    1. FALSE: The outlier should not be removed from the regression analysis
    2. TRUE: The outlier may be removed from the regression analysis, but this should be reported
    3. FALSE: The Mahalanobis value of the outlier must be reported in the manuscript
    4. FALSE: Multiple answers are good
