Question

the data below show the numbers of miles driven to work each day by the employees of a small company.
15, 25, 13, 15, 18, 20, 22, 24
the mean of the data is 19 miles. what is the mean absolute deviation of the data?
1.6
0.125
3.75
0

Explanation:

Step1: Find absolute deviations

$|15-19|=4$, $|25-19|=6$, $|13-19|=6$, $|15-19|=4$, $|18-19|=1$, $|20-19|=1$, $|22-19|=3$, $|24-19|=5$

Step2: Sum the absolute deviations

$4+6+6+4+1+1+3+5=30$

Step3: Calculate mean absolute deviation

$\frac{30}{8}=3.75$

Answer:

3.75
