To find the Mean Absolute Deviation (MAD), we first need to find the mean of the test scores:
(55 + 60 + 70 + 70 + 75 + 75 + 75 + 80 + 80 + 85 + 85 + 85 + 85 + 90 + 90 + 95 + 100) / 17 = 80.59
Next, we calculate the absolute deviation of each score from the mean:
|55 - 80.59| = 25.59
|60 - 80.59| = 20.59
|70 - 80.59| = 10.59
|70 - 80.59| = 10.59
|75 - 80.59| = 5.59
|75 - 80.59| = 5.59
|75 - 80.59| = 5.59
|80 - 80.59| = 0.59
|80 - 80.59| = 0.59
|85 - 80.59| = 4.41
|85 - 80.59| = 4.41
|85 - 80.59| = 4.41
|85 - 80.59| = 4.41
|90 - 80.59| = 9.41
|90 - 80.59| = 9.41
|95 - 80.59| = 14.41
|100 - 80.59| = 19.41
Then, we find the mean of these absolute deviations:
(25.59 + 20.59 + 10.59 + 10.59 + 5.59 + 5.59 + 5.59 + 0.59 + 0.59 + 4.41 + 4.41 + 4.41 + 4.41 + 9.41 + 9.41 + 14.41 + 19.41) / 17 = 8.56
The Mean Absolute Deviation (MAD) of the science test scores from Ms. O’Donnell’s class is 8.56.
Here are the science test scores from Ms. O’Donnell’s class:
55, 60, 70, 70, 75, 75, 75, 80, 80, 85, 85, 85, 85, 90, 90, 95, 100

wrong my guy
Apologies for the error. Let's recalculate the Mean Absolute Deviation (MAD) correctly.
First, let's find the mean of the test scores:
(55 + 60 + 70 + 70 + 75 + 75 + 75 + 80 + 80 + 85 + 85 + 85 + 85 + 90 + 90 + 95 + 100) / 17 = 80
Next, calculate the absolute deviation of each score from the mean:
|55 - 80| = 25
|60 - 80| = 20
|70 - 80| = 10
|70 - 80| = 10
|75 - 80| = 5
|75 - 80| = 5
|75 - 80| = 5
|80 - 80| = 0
|80 - 80| = 0
|85 - 80| = 5
|85 - 80| = 5
|85 - 80| = 5
|85 - 80| = 5
|90 - 80| = 10
|90 - 80| = 10
|95 - 80| = 15
|100 - 80| = 20
Now, find the mean of these absolute deviations:
(25 + 20 + 10 + 10 + 5 + 5 + 5 + 0 + 0 + 5 + 5 + 5 + 5 + 10 + 10 + 15 + 20) / 17 = 8.82
