Sample Size Calculator For A Mean
Sample Size Calculator For A Mean: a planned Super Calculator tool. Covers target margin of error. Stub page while the tool and its worked example are prepared.
Sample Size Calculator For A Mean is a planned calculator in the mathematics section of Super Calculator, covering statistics and probability.
What this calculator will compute
Inputs: target margin of error, population standard deviation estimate, confidence level (%) and population size (optional).
Outputs: required sample size, adjusted sample size and achieved margin at that n.
Formula, recorded as scope and not yet verified against a primary source: n = (z * sigma / E)^2 for a target margin of error E, iterated with the t critical value where sigma is estimated. Finite population correction: n_adj = n / (1 + (n - 1)/N).
