The two dot plots below show the heights of some sixth graders and some seventh graders:
2 answers:
Answer: The variability in the heights of the sixth graders is 2 times the variability in the height of the seventh graders.
Step-by-step explanation:
Since we have given tha t
Mean absolute deviation for the first set of data = 1.2
Mean absolute deviation for the second set of data = 0.6
We need to find the number of times the variability in the height of the seventh grade is the variability in the heights of the sixth graders.
So, our expression becomes
Hence, the variability in the heights of the sixth graders is 2 times the variability in the height of the seventh graders.
