I apologize for the mistake in my previous response. Let's calculate the mean absolute deviation (MAD) for the dataset provided.

First, let's calculate the mean of the dataset:
(106 + 122 + 134 + 150 + 120 + 92 + 75) = 799
799 / 7 = 114.1

Next, we calculate the absolute deviations of each data point from the mean:
|106 - 114.1| = 8.1
|122 - 114.1| = 7.9
|134 - 114.1| = 19.9
|150 - 114.1| = 35.9
|120 - 114.1| = 5.9
|92 - 114.1| = 22.1
|75 - 114.1| = 39.1

Now, calculate the mean of the absolute deviations:
(8.1 + 7.9 + 19.9 + 35.9 + 5.9 + 22.1 + 39.1) = 139.9
139.9 / 7 = 19.97

Therefore, the mean absolute deviation for this dataset is approximately 19.9.

Answer 4

the answer is actually 19.8 but i will give that 1 2 u

I apologize for the slight error in my previous response. Thank you for pointing that out. If the answer provided is calculated as 19.8, then that is the correct mean absolute deviation for the dataset. Thank you for your understanding.
