Question

Here is some data showing the age and value of 12 cars.
Draw a scatter diagram in your book and state the coordinates of the point that is most likely an outlier.

Age (years) 4 6 5 8 3 1 2 4 7 7 6 5
Value (£ 000's) 41 37 4 18 66 80 62 51 25 45 27

Answer 1

By graphing the data set, we conclude that the outlier is (5, 4).

Which point is most likely an outlier?

The outlier point will be the "most isolated point" of the data set.

It is easily identified when graphed, as you will see a group of points and another one isolated, which is the outlier.

The scatter diagram can be seen below, there you can see that the outlier is point C, which is the third point on the data set, which is (5, 4).

Then we conclude that the outlier is (5, 4).
