The outlier is far from the group in the x and y directions, and therefore, has a strong influence on the correlation which in turn affects the slope of the line. What is the effect of an outlier on the correlation and slope of the line?
1) The outlier increases the correlation and slope of the line
2) The outlier decreases the correlation and slope of the line
3) The outlier has no effect on the correlation and slope of the line
4) The effect of the outlier on the correlation and slope of the line cannot be determined
