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

Case: absolute deviation

Method:

Step 1: Find the mean

`\begin{gathered} \bar{x}=(2+4+5+7+10+13+15)/(7) \\ \bar{x}=(56)/(7) \\ \bar{x}=8 \end{gathered}`

The diagram:

The absolute deviation:

`\begin{gathered} m=(6+4+3+1+2+5+7)/(7) \\ m=(28)/(7) \\ m=4\text{ }years \end{gathered}`

Final answer:

The absolute deviation from the mean age is 4 years
