The formula for MAD (mean absolute deviation) =
Where x_i are the each individual values (stated)
XBar is the average value
n is the number of data
First, let's find XBar, or the average. We add up all the 4 numbers and divide by 4 to get:
XBar = (262+313+393+323)/4=322.75
<em>Now, let's calculate MAD:</em>
<em>MAD = </em>
<em />
<em>MAD = 35.25</em>
