Paste or type a list of numbers to get all the common statistics at once.
How it works
Mean = sum Γ· count. Median = the middle value when sorted. Mode = the most common value.
Standard deviation measures spread. Use the sample version (n β 1) for a sample of a bigger group, and the population version (n) when you have every value.
