What is the variance for the following population of scores? Scores: 5, 2, 5, 4

What is the variance for the following population of scores?

Scores: 5, 2, 5, 4

Expert Solution

mean =

x x - (x - )²

5 1 1

2 - 2 4

5 1 1

4 0 0

-------------------------------------------

Total 6

So

Variance =

So,

Answer is:

1.5
