Question

In the data set {(7,7);(3,10);(5,9);(2,12);(0,1);(6,4);(4,10);(8,6)}, which point is a possible outlier? please help :(

Answer 1

Answer: Choice D

(0,1)

==================================================

Step-by-step explanation:

Plot all of the points on the same xy grid as shown below.

The majority of the points cluster together somewhat. In this cluster we have a downward trend (aka negative correlation). As x gets bigger, y gets smaller, and vice versa.

Highlighted in red is the point (0,1) which is fairly separate from the main cluster of other black points. This is the outlier that will pull the regression line away from the main cluster of points.
