The answer is to the problem is 120 °
Solution: We are given below data:

Now to find the mean deviation, we use the below formula:

Where:
represents the summation
X, represents the observation.
represents the mean
N represents the number of observation.


Therefore, the mean deviation is:

= 4
270 degrees this because when you count each angle it is 90 degrees then 180 degrees then 270
