Frequently Asked Questions
What's the difference between population and sample statistics?
This calculator computes population statistics (using N in denominators). For sample statistics, the standard deviation would use N-1. Population statistics are used when you have data for the entire group you're studying.
How do I interpret skewness and kurtosis values?
Skewness measures asymmetry: values near 0 indicate symmetry, positive values indicate right tail, negative values indicate left tail. Kurtosis measures tail heaviness: positive values indicate heavy tails, negative values indicate light tails.
What data formats can I use?
You can enter data as a comma-separated list, CSV format (one value per line), or frequency format (value:frequency). The calculator automatically detects and parses your input format.
Is there a limit to how much data I can analyze?
Yes, the calculator supports up to 10,000 data points to ensure fast performance. For larger datasets, consider using specialized statistical software.
