Answer:

4\dfrac{2}{7}

Step-by-step explanation:

How to calculate the mean absolute deviation:

<u>Step 1:</u> Calculate the mean.

\text{Mean}=\dfrac{49+55+52+46+47+42+38}{7}=47

<u>Step 2:</u> Calculate how far away each data point is from the mean using positive distances. These are called absolute deviations.

\begin{array}{ccccccc}\text{Sun}&\text{Mon}&\text{Tue}&\text{Wed}&\text{Thu}&\text{Fri}&\text{Sat}\\49&55&52&46&47&42&38\\2&8&5&1&0&5&9\end{array}

<u>Step 3:</u> Add those deviations together.

\sum|\text{mean}-x_i|=2+8+4+1+0+5+9=30

<u>Step 4:</u> Divide the sum by the number of data points.

\text{MAD}=\dfrac{\sum|\text{mean}-x_i|}{n}=\dfrac{30}{7}=4\dfrac{2}{7}
