Question

Calculate the variance for the following population of N = 5 scores:
2, 13, 4, 10, 6

Answer 1

Answer:

16

Step-by-step explanation:

(1) Get the mean: (2 + 13 + 4 + 10 + 6) / 5 = 7

(2) Variance Formula: Σ(x-mean)^2)/N

-> (2-7)^2 + (13-7)^2 + (4-7)^2 + (10-7) ^2 + (6-7)^2

                                        5

= 16
