Calculate population and sample standard deviation with detailed step-by-step solutions and statistical analysis
Enter at least 2 values
s = Sample standard deviation
σ = Population standard deviation
x̄ = Sample mean
μ = Population mean
n = Sample size
N = Population size
Population standard deviation (σ) is used when you have data for the entire population and divides by N. Sample standard deviation (s) is used when you have a sample from a larger population and divides by (n-1) to account for the degrees of freedom. Sample standard deviation is more commonly used in practice.
