To compare the variability in the heights of the seventh graders to the variability in the heights of the sixth graders, we can calculate the ratio of their mean absolute deviations (MAD).
MAD ratio = MAD of seventh graders / MAD of sixth graders
MAD ratio = 0.6 / 1.2
MAD ratio = 0.5
This means that the variability in the heights of the seventh graders is approximately half the variability in the heights of the sixth graders.
So, the answer is 0.5, which is equivalent to 0.3 when rounded to the tenths place.
Therefore, the answer is 0.3.
The two dot plots below show the heights of some sixth graders and some seventh graders: The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 0.6. Approximately how many times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders? (Round all values to the tenths place.)
