−3, 3, 0, 3, −3 What is the standard deviation of the numbers above

2.683

Explanation:

Given the data: X: −3, 3, 0, 3, −3

Mean(m) = ΣX / n

n = number of observations = 5

(-3 + 3 + 0 + 3 + - 3) / 5

= 0 / 5

m = 0

√(Σ(x - m)² / n)

(-3 - 0)^2 + (3 - 0)^2 + (0 - 0)^2 + (3 - 0)^2 + (- 3 - 0)^2

= 9 + 9 + 0 + 9 + 9 / 5

= 36 / 5

= 7.2

√7.2

= 2.683
