Webb19 apr. 2024 · 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. With that range, you know that at least half the observations fall within it, and no more than half ... WebbStandard deviation (σ) calculator with mean value & variance online.
