Consequently, Chebyshev’s Theorem tells you that at least 75% of the values fall between 100 ± 20, equating to a range of 80 – 120. Conversely, no more than 25% fall outside that range. An interesting range is ± 1.41 standard deviations.

WebTo compute the probability that an observation is within two standard deviations of the mean (small differences due to rounding): Pr (μ − 2σ ≤ x ≤ μ + 2σ) = F (2) − F (−2) = 0.9772 − (1 − 0.9772) = 0.9545 or 95.45%. This is related to confidence interval as used in statistics: μ ± 2σ is approximately a 95%.
WebStandard deviation in statistics, typically denoted by σ, is a measure of variation or dispersion (refers to a distribution's extent of stretching or squeezing) between values in a set of data.
