Calculate standard-deviation-of-10_-12_-14_-16_-18
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 = (-10 + -12 + -14 + -16 + -18) ÷ 5
= -70 ÷ 5 = -14
For each value, subtract the mean and square the result:
(-10 − -14)2 = (4)2 = 16
(-12 − -14)2 = (2)2 = 4
(-14 − -14)2 = (0)2 = 0
(-16 − -14)2 = (-2)2 = 4
(-18 − -14)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
