Statistics Calculators
Summarize a data set: find the mean, median and mode, and compute variance and standard deviation for either a full population or a sample, with the denominator stated explicitly.
Standard Deviation
Population or sample standard deviation and variance, with the denominator (n or n−1) stated.
e.g. Population of 8 valuesStepsDecimal resultMultiple methods
Combinations & Permutations
Compute nCr, nPr and n! with integer validation, overflow handling and identity checks.
e.g. C(5, 2)StepsExact resultVerified
Mean, Median, Mode
Mean, median and mode of a data set, with sorted values, count, sum, min and max.
e.g. 4, 8, 15, 16, 23, 42StepsDecimal resultVerified
Probability
Event probability = favourable ÷ total outcomes, with the complement, as fraction, decimal and percent.
