Answer with explanation

Data Set A: 2,9,9,2,5,6,4

Data Set B: 7,1,6,9,0,2,0

Data Set C: 9,2,4,8,3,7,1

Data Set D: 2,3,5,9,4,9,1

Mean of a data set

Mean of Data set A=

Mean of Data set B=

Mean of Data set C=

Mean of Data set D=

→Modulus of Difference between Mean and variate in data set A

=2.70(approx)→MAD

→Modulus of Difference between Mean and variate in data set D

=2.53 (approx)→MAD

→Data Set B, has maximum Mean Absolute Deviation,among four data sets,which will be helpful in determining ,the variation.

Option B: Data Set ,B:→ {7,1,6,9,0,2,0} ,mean absolute deviation (MAD) is a good indicator of variation of the data.
