Detailed Answer Key

Problem 1 : 

Describe the spread, center, and shape of the dot plot given below. 

Solution : 

The data values are spread out from 3 to 7 with no outliers.

The data has a cluster from 3 to 7 with one peak at 5, which is the center of the distribution.

The distribution is symmetric. The data values are clustered around the center of the distribution.

Problem 2 : 

Describe the spread, center, and shape of the dot plot given below. 

Solution : 

The data values are spread out from 1 to 9. The data value 1 appears to be an out lier.

The data has a cluster from 6 to 9 with one peak at 9, which is the greatest value in the data set.

The distribution is not symmetric. The data values are clustered at one end of the distribution.

Problem 3 : 

Describe the spread, center, and shape of the dot plot given below. 

Solution : 

The data values are spread out from 0 to 11. The data value 11 appears to be an out lier.

The data has a cluster from 0 to 7 with one peak at 2, which is the greatest value in the data set.

The distribution is not symmetric. The data values are clustered at one end of the distribution.

Problem 4 : 

Describe the spread, center, and shape of the dot plot given below. 

Solution :

Solution : 

The data values are spread out from 0 to 11 with no outliers.

The data has a cluster from 0 to 11 with one peak at 5, which is the center of the distribution.

The distribution is symmetric. The data values are clustered around the center of the distribution.
