Calculate standard-deviation-of-2_-4_-6_-8_-10
Calculate mean, median, mode, standard deviation, variance and more — step by step.
To find the population standard deviation of 5 values, follow the step-by-step solution below.
Mean = (-2 + -4 + -6 + -8 + -10) ÷ 5
= -30 ÷ 5 = -6
For each value, subtract the mean and square the result:
(-2 − -6)2 = (4)2 = 16
(-4 − -6)2 = (2)2 = 4
(-6 − -6)2 = (0)2 = 0
(-8 − -6)2 = (-2)2 = 4
(-10 − -6)2 = (-4)2 = 16
Variance = (16 + 4 + 0 + 4 + 16) ÷ 5
= 40 ÷ 5 = 8
The standard deviation is the square root of the variance:
σ = √8 = 2.828427
Standard deviation (σ) = 2.828427
