A worked example
Dataset 1, 2, 3 → mean 2, median 2, population standard deviation approximately 0.81649658 and sample standard deviation 1.
What to know
Population variance divides by n; sample variance divides by n−1 and requires at least two values. All equally most frequent values are reported as modes; if every value occurs once, no mode is reported.
Supported inputs and limits
10,000 values, each within ±10¹⁵.
