Question
What is the mean absolute deviation or NAD of the times we have obstacle course test time and minutes and we have numbers 5678 9101112 and 13 and we have a dot at five a dot at six and a dot at 10 so Mad equals how many minutes

To calculate the Mean Absolute Deviation (MAD), we first need to find the mean of the obstacle course test times.
Mean = (5 + 6 + 7 + 8 + 10 + 11 + 12 + 13) / 8 = 8.75
Next, we find the absolute deviation of each time from the mean:
|5 - 8.75| = 3.75
|6 - 8.75| = 2.75
|7 - 8.75| = 1.75
|8 - 8.75| = 0.75
|10 - 8.75| = 1.25
|11 - 8.75| = 2.25
|12 - 8.75| = 3.25
|13 - 8.75| = 4.25
Now, we find the average of these absolute deviations:
(3.75 + 2.75 + 1.75 + 0.75 + 1.25 + 2.25 + 3.25 + 4.25) / 8 ≈ 2.56
So, the Mean Absolute Deviation (MAD) of the obstacle course test times is approximately 2.56 minutes.
Mean = (5 + 6 + 7 + 8 + 10 + 11 + 12 + 13) / 8 = 8.75
Next, we find the absolute deviation of each time from the mean:
|5 - 8.75| = 3.75
|6 - 8.75| = 2.75
|7 - 8.75| = 1.75
|8 - 8.75| = 0.75
|10 - 8.75| = 1.25
|11 - 8.75| = 2.25
|12 - 8.75| = 3.25
|13 - 8.75| = 4.25
Now, we find the average of these absolute deviations:
(3.75 + 2.75 + 1.75 + 0.75 + 1.25 + 2.25 + 3.25 + 4.25) / 8 ≈ 2.56
So, the Mean Absolute Deviation (MAD) of the obstacle course test times is approximately 2.56 minutes.
