Module 8 Lesson 2: Statistical Variability and Comparing Populations
Jason wants to compare the mean height of the players on his favorite hockey and volleyball teams. He creates the dot plots shown below:
First dot plot is labeled Height of Hockey Players and shows 1 cross on 67, 1 cross on 69, 2 crosses on 70, 2 crosses on 71, 4 crosses on 72, 5 crosses on 73, 3 crosses on 74, 2 crosses on 76, and 1 cross on 78. Second dot plot is labeled Height of Volleyball Players and shows 1 cross on 73, 1 cross on 75, 1 cross on 76, 2 crosses on 78, 2 crosses on 79, 2 crosses on 80, 2 crosses on 81, 2 crosses on 82, and 3 crosses on 84
The mean absolute deviation is 1.83 inches for the hockey team and 2.53 inches for the volleyball team. Which of the following conclusions can be drawn from the data?
