WebMar 27, 2024 · standard deviation, in statistics, a measure of the variability (dispersion or spread) of any set of numerical values about their arithmetic mean (average; denoted by μ). It is specifically defined as the positive square root of the variance (σ2); in symbols, σ2 = Σ(xi − μ)2/n, where Σ is a compact notation used to indicate that as the index (i) changes … WebAug 22, 2024 · The standard deviation (SD) measures the extent of scattering in a set of values, typically compared to the mean value of the set. [1] [2] [3] The calculation of the SD depends on whether the dataset is a sample or the entire population. Ideally, studies would obtain data from the entire target population, which defines the population parameter.
