Answer:
16.5
Step-by-step explanation:
Given data to us is ,
- 20, 15, 14, 16, 17, 12, 20, 22 .
Arrange it in ascending order .
= 12 , 14 , 15 , 16 , 17 , 20 , 20 , 22
The middle most observation will be median in case n is odd and average of middlemost observations if n is even , that is n = 8 .
=> Middlemost observations = 16 , 17
=> Mean = 16 + 17 /2 = 33/2 = 16.5
