The "sample" with "mean absolute deviation" indicate about a sample mean absolute deviation is being used as an estimator of the mean absolute deviation of a​ population

  • Mean of the sample MAD=3.3
  • Population MAD =6.4

<h3>What does this indicate about a sample mean absolute deviation used as an estimator of the mean absolute deviation of a​ population?</h3>

1/n \sum_i-1^{n} |x_i -m(X)|

In conclusion, for the corresponding same to mean

the sample  mean absolute deviation

7,7  ↔         0

7,21  ↔         7

7,22         ↔    7.5

21,7        ↔          7

21,21 ↔     0

21,22 ↔    0.5

22,7   ↔     7.5
