Common questions
Population or sample standard deviation?
Population divides by n; sample divides by n minus 1 and is the right choice when your numbers are a sample of a larger group. Both are shown.
How are quartiles calculated?
By linear interpolation between the closest ranks, which is one of the common methods and matches many spreadsheet tools.
Why are the geometric and harmonic means sometimes blank?
They are only defined for positive numbers, so they are omitted if any value is zero or negative.
