FAQ
What's the difference between population and sample standard deviation?
Use population standard deviation when your numbers represent the entire dataset, and sample standard deviation when they're a sample drawn from a larger population. Sample standard deviation is always slightly larger.
What happens if there's more than one mode?
If multiple values tie for the highest frequency, all of them are shown. If every value appears the same number of times, it shows "No mode".
Does this support decimal numbers?
Yes โ both whole numbers and decimals are supported.
