Standard Deviation Calculator
Standard Deviation: a planned Super Calculator tool. Covers data column. Stub page: the tool, its formula and a worked example are not published yet. Scope is.
Standard Deviation Calculator is a planned calculator in the mathematics section of Super Calculator, covering descriptive and summary statistics.
What this calculator will compute
Inputs: data column and sample or population basis.
Outputs: standard deviation, variance, mean, sum of squared deviations, step-by-step working and standard error.
Formula, recorded as scope and not yet verified against a primary source: Population sigma = sqrt(sum((x - mu)^2)/N). Sample s = sqrt(sum((x - xbar)^2)/(n-1)), where the n-1 denominator makes the variance estimator unbiased.
