Use the dot plots representing the number of siblings of students in each class.

Visually Compare the 2 Dot Plots

• All the data are 7 siblings or fewer; There is a greater spread in the number of siblings in Mr. Walker’s class.

• All the data are 7 siblings or fewer; There is a greater spread in the number of siblings in Mr. Whites’s class.

• All the data are 6 siblings or fewer; There is a greater spread in the number of siblings in Mr. Walker’s class.

• All the data are 6 siblings or fewer; There is a greater spread in the number of siblings in Mr. Whites’s class

Compare the shapes of the box plots.

• Overall the scores of Class A are slightly higher, and the ranges of the box plots appear to be very similar.

• Overall the scores of Class B are slightly higher, and the ranges of the box plots appear to be very similar.

• Overall the scores of Class A are slightly higher, and the ranges of the box plots appear to be very far different.

• Overall the scores of Class B are slightly higher, and the ranges of the box plots appear to be very far different.

Lydia's math test scores are 10, 50, 75, 80, 82, 82, and 97. The lowest score will not be counted. How does the original mean score compare with the mean, after the lowest score is removed?

• The final mean is higher than the original.

• The final mean is lower than the original.

• The final mean is the same as the original.

• The relationship cannot be determined.
