WILL GIVE BRAINLIEST AND 50 POINTS
Robin’s scores: 99, 108, 102, 107, 119

Mean = 107; MAD = 5.2

Evelyn’s scores: 125, 137, 138, 145, 145

Mean = 138; MAD = 5.6

Answer:

Hello, I only know the first part of the question.  

Explain what the mean absolute deviation is in general.

The mean absolute deviation of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. In general the mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.

Hope this helps some :)

Answer:

sample response - The MAD describes the average distance from a data point to the mean. It measures variability. For this data, it shows that Evelyn’s scores varied slightly more than Robin’s
