SALES Nate is keeping track of how much people spent at the school bookstore in one day. Find the mean absolute deviation for the data to the nearest tenth: $1, 1, 2, 3, 4, 5, 12$

Short Answer

Expert verified

The mean absolute deviation for the data is $2.57$ .

Step by step solution

Step 1. Find the mean.

To find the mean, add the numbers and then divide by the number of values in the data set.

$\begin{array}{l} \overset{炉}{x} = \frac{1 + 1 + 2 + 3 + 4 + 5 + 12}{7} \\ = \frac{28}{7} \\ = 4 \end{array}$

Step 2. Find the sum.

Find the sum of the absolute values of the differences between each value in the set of data and the mean.

$\begin{array}{r} | 1 鈭� 4 | + | 1 鈭� 4 | + | 2 鈭� 4 | + | 3 鈭� 4 | + | 4 鈭� 4 | + | 5 鈭� 4 | + | 12 鈭� 4 | = 3 + 3 + 2 + 1 + 0 + 1 + 8 \\ = 18 \end{array}$

Step 3. Division.

Divide the sum by the number of values in the set of data.

$\frac{18}{7} = 2.57$

Therefore, the mean absolute deviation for the data is $2.57$ .
