The mean of data set A is 43.5 and the MAD is 3.7. The mean of data set B is 12.8 and the MAD is 4.1. ques #1: Which data set shows greater variability? Explain your reasoning.

ques #2: What differences would you expect to see when comparing the dot plots of the two data sets?

For questions one: its B

Step-by-step explanation:

since, Data set B shows a greater degree of variability because the distance between a data point(value) and the mean is 4.1. This also means that the data points in Set B are more spread out compared to the data points in Set A.

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

so, converting firstly the mixed fractions to improper fractions and then "adding".
