Acamping goods store has 5 models of waterproof flashlights. the 5 models sell for $23, $29, $14, $26, and $18.
what is the mean absolute deviation of the prices? round to the nearest cent, if necessary.

So we want to know what mean absolute deviation is of the prices of the 5 products. First we calculate the mean value x=(23+29+14+26+18)/5=22. Now we calculate the distance of each price and the mean value and those are v1=23-22=1, v2=29-22=7, v3=22-14=8, v4=26-22=4, v5=22-18=4. Now we take the mean value from our distances: M=(1+7+8+4+4)/5=4.8 and we got our mean absolute value.
