Enter your numbers, choose sample or population, then press Calculate—your mean, variance, and standard deviation appear instantly. Roughly 68 % of values in a normal distribution fall within one standard deviation of the mean (68-95-99.7 rule https://en.wikipedia.org/wiki/68%E2%80%9395%E2%80%9399.7_rule).
Input numbers, press “Calculate,” and the tool returns Mean Absolute Deviation (MAD) and Coefficient of Variation (CV). For example, 8 values—14 17 19 18 16 20 21 15—produce MAD ≈ 2.0 and CV ≈ 11 % (NIST Handbook, 2023).
