The answer is 2.2
To find the answer you need to find the distance between the mean and the number set(distance between 7 and 4 is 3 and so on..) once you have done this for every number add them up and divide it by how many numbers there are in the set.(In this case 10) and you should get your answer.(2.2)
Hope this helps!
