Julia measured the high temperature in her town for one week. Using the chart below, find the mean absolute deviation for the high temperatures. Be sure to show your work for finding:
graph:sunday:50 monday:56 tuesday:52 wednesday:46 thursday:48 friday:42 saturday:38
I’m pretty sure this is correct. Explanation:
49 + 55 + 52 + 46 + 47 + 42 + 38 = 329
There are seven values, so divide by seven.
329 / 7 = 47
47 is the mean
Now you find the differences from values to the mean.
49 - 47 = 2
55 - 47 = 8
52 - 47 = 5
47 - 46 = 1
47 - 47 = 0
47 - 42 = 5
47 - 38 = 9
You then add all the differences, which will get you 30.
Then divide 30 by the number of differences which is 7.
30 / 7 = 4.2857
