Makayla conducted an experiment on the 7th grade class. She took the resting heart rate of 20 of her classmates and then had them walk for one mile and took their heart rates again. She used the data that she collected to make the dot plots below.
Based on Makayla's data, the mean resting heart rate is 82 beats per minute with a mean absolute deviation of
. The mean heart rate after walking one mile is 96 beats per minute with a mean absolute deviation of
.
From the data, Makayla concluded the students' heart rates had less variability before or after walking one mile?
