Frequently asked questions
What is the difference between population and sample standard deviation?
The population version divides by n; the sample version divides by n − 1 to correct bias when estimating from a sample.
What is the mode if no value repeats?
If every value appears once the data set has no mode; if several values tie for most frequent, all of them are modes.
How should I enter my data?
Type the numbers separated by commas or spaces, for example 4, 8, 15, 16, 23, 42.
