Calculate the mean and mean absolute deviation of these two data sets and use that to compare the two sets of data. Set A: 4, 6, 7, 8, 5, 6
Set B: 5, 7, 4, 8, 9, 9

Set B has a lesser average and less consistent data values than Set A.

Set B has a greater average but has less consistent data values than Set A.

Set B has a greater average and is more consistent data values than Set A.
