PDF Variance and standard deviation (ungrouped data) Since the variance is measured in terms of x2,weoften wish to use the standard deviation where σ = √ variance. The standard deviation, unlike the variance, will be measured in the same units as the original data. In the above example σ = √ 31.11=5.58 (2 dp) Exercises Find the variance and standard deviation of the following correct to 2 ...

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.
