Question

The stem and leaf plot below displays a set of data recorded in the North Pole.

Stem:
-3, -2, -1, 0, 1, 2, 3

Leaf:
5,2,2,1,0,7,7,7,5,3,2,0,-9,-6,-4,-1,-1,0,3,6,1,2,5

Which box plot closely resembling the data set within the stem and leaf plot, represents a data set with outliers?

Answer 1

plot B

Explanation:

-3

-2 goes with 5,2,2,1,0

-1 goes with 7,7,7,5,3,2,0

0 goes with -9,-6,-4,-1,-1,0,3,6

1 goes with 1,2

2 goes with 6

3

This means there should be no data in our box and whisker plot until a whisker starts at -25. This eliminates plot A

We will also stop our last whisker at 26 . This eliminates plot C

We have 23 data points. So the median point is 12

The 12th point is -10

The middle of our box should be at -10 This eliminates plot D

Our answer is plot B
