Question

The tables show the battery lives (in hours) of two brands of laptops. Which brand's battery lives are more spread out? Explain​

Answer 1

Absolute Mad Deviation is used to see how spread out data is, you find the mean of data then subtract the mean from each number (absolute value) and then find the mean with the subtracted numbers.
Brand A MAD: 2.6925
Brand B MAD: 1.05
It’s Brand A :)
