Question

Find the mean absolute deviation (MAD), by

averaging the differences from the mean.
Number of Newspapers Delivered
19, 14, 19, 21, 17
|19-18 = 1
14-18=4
19-18=1
121-18 = 3
|17-18 = 1
MAD = [?]

Answer 1

The mean absolute deviation (MAD) is calculated by averaging the absolute differences between each data point and the mean. In this case, the data points are the number of newspapers delivered: 19, 14, 19, 21, and 17. The mean of these numbers is 18.

The absolute differences between each data point and the mean are: |19-18| = 1, |14-18| = 4, |19-18| = 1, |21-18| = 3, and |17-18| = 1.

The sum of these absolute differences is 1 + 4 + 1 + 3 + 1 = 10. Dividing this sum by the number of data points (5) gives us the MAD: 10/5 = 2.

So the MAD for this data set is 2.

Answer 2

Explanation:

To find the mean absolute deviation (MAD) of the number of newspapers delivered, we first need to calculate the mean. Adding up all the numbers and dividing by the total number of values gives us a mean of 18. Next, we calculate the absolute difference between each number and the mean, which gives us the following values: 1, 4, 1, 3, 1. Finally, we average these values by adding them up and dividing by the total number of values, which is 5. Therefore, the MAD of the number of newspapers delivered is 2.
