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.

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

Therefore, the Mean Absolute Deviation (MAD) of the science test scores from Ms. O’Donnell’s class is 8.82. Thank you for your patience.

I apologize for the mistake in my previous responses. Let's recalculate the Mean Absolute Deviation (MAD) correctly using the formula for MAD:

1. 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

2. 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

3. Find the sum of these absolute deviations:

25 + 20 + 10 + 10 + 5 + 5 + 5 + 0 + 0 + 5 + 5 + 5 + 5 + 10 + 10 + 15 + 20 = 150

4. Calculate the Mean Absolute Deviation (MAD):

MAD = 150 / 17 = 8.82

Therefore, the correct Mean Absolute Deviation (MAD) of the science test scores from Ms. O’Donnell’s class is 8.82. Thank you for your patience.

I apologize for the errors in my previous responses. Let's find the Mean Absolute Deviation (MAD) correctly this time.

1. 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

2. 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
|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

3. Find the sum of these absolute deviations:

25 + 20 + 10 + 10 + 5 + 5 + 5 + 0 + 0 + 5 + 5 + 5 + 5 + 10 + 10 + 15 + 20 = 150

4. Calculate the Mean Absolute Deviation (MAD):

MAD = 150 / 17 = 8.82

Therefore, the correct Mean Absolute Deviation (MAD) of the science test scores from Ms. O’Donnell’s class is 8.82.

I apologize for the errors. Let's re-calculate the Mean Absolute Deviation (MAD) correctly:

1. 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

2. Calculate the absolute deviation of each score from the mean and sum them up:

|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

Sum of absolute deviations = 25 + 20 + 10 + 10 + 5 + 5 + 5 + 0 + 0 + 5 + 5 + 5 + 5 + 10 + 10 + 15 + 20 = 150

3. Calculate the Mean Absolute Deviation (MAD):

MAD = Sum of absolute deviations / Number of data points = 150 / 17 ≈ 8.82

Therefore, the Mean Absolute Deviation (MAD) of the science test scores from Ms. O’Donnell’s class is approximately 8.82. Thank you for your patience.
