Vicki measured the midnight temperatures in 4 locations in Alaska. The temperatures were - 7, - 2, 1, 4.

What is the mean absolute deviation of the temperatures?

The mean is - 1

1. Find the mean of the dа ta: (-7 - 2 + 1 + 4) / 4 = - 1

2. Find the absolute value of differences between each data an the mean:

1) |-7 - (-1) | = |-7 + 1| = |-6| = 6

2) |-2 - (-1) | = |-2+1| = |-1| = 1

3) |1 - (-1) | = |1+1| = |2| = 2

4) |4 - (-1) | = |4+1|=|5|=5

3) Calculate the mean of those differences:

(6 + 1 + 2 + 5) / 4 = 14/4 = 3.5
