To find the mean absolute deviation, first find the mean of the dataset:

Mean = (106 + 122 + 134 + 150 + 120 + 92 + 75) / 7 = 799 / 7 = 114.1

Next, find the absolute deviations for each data point:

|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

Add up all the absolute deviations:

8.1 + 7.9 + 19.9 + 35.9 + 5.9 + 22.1 + 39.1 = 139.9

Now, find the mean of the absolute deviations:

Mean absolute deviation = 139.9 / 7 = 19.98

Rounding to the nearest tenth:

Mean absolute deviation = 19.9

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

Answer 2

you mean 19.8?
