Is Standard Deviation Unbiased at Patrick Purcell blog

Is Standard Deviation Unbiased. The real standard deviation is $ \frac1{2\sqrt{3}}$, a multiple of $ \frac{\sqrt{3}}{\sqrt{2}}$ larger. The process of taking the square root of the variance to find the standard deviation introduces some bias. That gets into the nonlinear transformation of the data. The reason for this is because when we calculate the sample standard deviation, we tend to underestimate the true variability in the. The standard deviation measures the spread of a set of data values. While this is not an unbiased estimate, it is a less biased estimate of standard deviation: It is better to overestimate rather than. A high standard deviation indicates a wide spread of data values, while a low standard deviation indicates a narrow.
