Question

The following data show the distances (in miles) from the homes of off-campus statistics students to the college. Create a stem plot using the data. 0.5; 0.7; 1.1; 1.2; 1.2; 1.3; 1.3; 1.5; 1.5; 1.7; 1.7; 1.8; 1.9; 2.0; 2.2; 2.5; 2.6; 2.8; 2.8; 2.8; 3.5; 3.8; 4.4; 4.8; 4.9; 5.2; 5.5; 5.7; 5.8; 8.0 Which are the outliers?

Answer 1

Answer:

See the plot below.

For this case we can consider as an outlier the value 8.0 since is far away from the other points

Step-by-step explanation:

For this case we can create the stem plot like this:

Stem      Leaf

 0      |     5 7

 1       |     1 2 2 3 3 5 5 7 7 8 9

 2      |     0 2 5 6 8 8 8

 3      |     5 8

 4      |     4 8 9

 5      |     2 5 7 8

 6      |

 7      |

 8      |    0

Notation : "1 |1 means 1.1 for example and 3|5 means 3.5"

By definition an outlier is "an observation that lies an abnormal distance from other values in a random sample from a population"

For this case we can consider as an outlier the value 8.0 since is far away from the other points
