The two dot plots below compare the forearm lengths of two groups of schoolchildren:


Two dot plots are shown one below the other. The title for the top dot plot is Forearm Length, Group A and the title for the bottom plot is Forearm Length, Group B. Below the line for each dot plot is written Length followed by inches in parentheses. There are markings from 11 to 14 on each line at intervals of one. For the top line there are 3 dots above the second mark, 4 dots above the third mark, and 3 dots above the fourth mark. For the bottom line there are 3 dots above the first mark, 5 dots above the second mark, and 2 dots above the third mark.


Based on visual inspection of the dot plots, which group appears to have the longer average forearm length?


Group B, because three children in the group have the least forearm length of 11 inches

Group A, because three children in the group have the least forearm length of 11 inches

Group A, because seven children have a forearm length longer than 12 inches

Group B, because two children have a forearm length longer than 12 inches

Answer 1

Using the dot plot, the correct option regarding the group that appears to have the longer average forearm length is:

Group A, because seven children have a forearm length longer than 12 inches
