Frequently asked questions
What's the difference between sample and population standard deviation?
Sample standard deviation divides by n − 1 and estimates the spread of a larger population from a sample. Population standard deviation divides by n and is used when you have every value.
How are quartiles calculated?
With linear interpolation between ranks — the same method as Excel's QUARTILE.INC and NumPy's default percentile.
Can I paste a column straight from Excel?
Yes. Copied cells arrive separated by new lines or tabs, which the calculator understands. Thousands separators like 1,200 are read correctly.
