Z Score Calculator
Z Score: a planned Super Calculator tool. Covers raw value x and population mean mu. Stub page: the tool, its formula and a worked example are not published.
Z Score Calculator is a planned calculator in the mathematics section of Super Calculator, covering statistics and probability.
What this calculator will compute
Inputs: raw value x, population mean mu, standard deviation sigma and sample size n (optional).
Outputs: z score, two-tailed p value and percentile (%).
Formula, recorded as scope and not yet verified against a primary source: Standard score z = (x - mu) / sigma for a population, or z = (x - xbar) / s for a sample. For a sampling distribution of means the standard error replaces sigma: z = (xbar - mu) / (sigma / sqrt(n)).
