The mean absolute deviation of the data in the image given is: 1.5.
What is the Mean Absolute Deviation?
The mean absolute deviation can be described as the average distance between each data value of a data set and its mean.
Thus:
Let's find the average of the data set:
Each data in the data set are 7, 2, 4, 3.
Mean = (7 + 2 + 4 + 3)/4
Mean = 4
Therefore:
Mean absolute deviation = (|x1 - mean| + |x2 - mean| + ...)/N
(|x1 - mean| + |x2 - mean| +...) = (|7 - 4| + |2 - 4| + |4 - 4| + |3 - 4|) = 6
N = 4
Thus:
Mean absolute deviation = 6/4 = 1.5
Therefore, the mean absolute deviation of the data in the image given is: 1.5.
