The mean absolute deviation of this data set is 1.25 which is nearest to the 1.1 option third is correct.
What is mean absolute deviation?
It is defined as the measure to show the variation in data set in other words between the mean and every data value, the distance known as the MAD.
We have data as shown in the picture in the form of frequency graph.
The mean = 11/4 = 2.75
The difference between each value and mean is shown in the attached table.
MAD = 5/4 = 1.25
The nearest value is 1.1.
Thus, the mean absolute deviation of this data set is 1.25 which is nearest to the 1.1 option third is correct.
