    The mean absolute deviation of a set of data is the average distance between each data value and the mean. 2. Find the distance between each data value and the mean. That is, find the absolute value of the difference between each data value and the mean.

    ^^^ Find the mean, and subtract all the values from the mean, then find the mean of that. For example. 2, 3, 3, 4, 6, 8, 9, 9 Find the mean. \(\sf \dfrac{2 + 3 + 3 + 4 + 6 + 8 + 9 + 9}{8} \rightarrow 5.5\) Now subtract all the values from it. \(\sf 5.5 - 2 = 3.5\) \(\sf 5.5 - 3 = 2.5\) \(\sf 5.5 - 3 = 2.5\) \(\sf 5.5 - 4 = 1.5\) \(\sf 6 - 5.5 = 0.5\) \(\sf 8 - 5.5 = 2.5\) \(\sf 9 - 5.5 = 3.5\) \(\sf 9 - 5.5 = 3.5\) Find the mean of these values. \(\sf \dfrac{3.5 + 2.5 + 2.5 + 1.5 + 0.5 + 2.5 + 3.5 + 3.5}{8} \rightarrow \color{#45D229}{\boxed{2.50}}\)
