Frequently asked questions
What separates the numbers?
Any mix of commas, spaces, tabs or new lines works — the tool extracts every number it can find, including decimals and negatives.
Population vs sample stddev?
Population divides by n and is used when you have the whole group; sample divides by n − 1 and is used when the data is a sample of a larger population.
