Question

there are seven cousins in the family agreed 2,4,5,7,10,13 and 15 years old use these ages to complete the diagram below then find the absolute deviation

Answer 1

SOLUTION:

Case: absolute deviation

Method:

Step 1: Find the mean

$\begin{gathered} \bar{x}=\frac{2+4+5+7+10+13+15}{7} \\ \bar{x}=\frac{56}{7} \\ \bar{x}=8 \end{gathered}$

The diagram:

The absolute deviation:

$\begin{gathered} m=\frac{6+4+3+1+2+5+7}{7} \\ m=\frac{28}{7} \\ m=4\text{ }years \end{gathered}$

Final answer:

The absolute deviation from the mean age is 4 years
