WebbSal explains a different variance formula and why it works! For a population, the variance is calculated as σ² = ( Σ (x-μ)² ) / N. Another equivalent formula is σ² = ( (Σ x²) / N ) - μ². If we need to calculate variance by hand, this alternate formula is easier to work with. Created by Sal Khan. Sort by: WebbThe code \times is used in LaTeX to make the symbol ×. The square root symbol is written using the command \sqrt {expression}. The n -th root is written using the command \sqrt [n] {expression}. The square root of a number can never be negative by definition. The root of a quadratic equation however, can be either positive or negative. WebbStandard deviation (sigma) around a normally-distribute mean represents where you'll find about 70% of the population. So if mean height is 5 feet and standard deviation is 1 foot, 70% of the population will be between 4-6 feet tall. 95% of the population will be between 2 standard deviations from the mean, or between 3-7 feet tall. poops perth
