Standard Deviation and Variance - Math is Fun A Sample: divide by N-1 when calculating Variance. All other calculations stay the same, including how we calculated the mean. Example: if our 5 dogs are just a sample of a bigger population of dogs, we divide by 4 instead of 5 like this: Sample Variance = 108,520 / 4 = 27,130. Sample Standard Deviation = √27,130 = 165 (to the nearest mm ...

Standard deviation and variance - Free Math Worksheets The standard deviation is useful because it gives information about how far away the data is from the arithmetic mean. Definition: Standard deviation is equal to the square root of the variance, i.e. σ = ∑ i = 1 k f i ( x i - μ) 2 ∑ i = 1 k f i. Therefore, $\sigma$ is the average deviation of values of numeric variable from its arithmetic mean.
