FAQ
What's the difference between population and sample standard deviation?+
Population (divide by n) is right when your numbers ARE the whole population. Sample (divide by n-1) is right when they're a sample drawn from a bigger population. Most school problems want sample.
When is mode 'none'?+
When every number appears the same number of times. The list has no most-frequent value.
