FAQ
- How is mode calculated? — The value(s) that appear most often. If all values are unique, "None (all unique)" is shown.
- What is the difference between population and sample standard deviation? — Population std dev divides by N; sample std dev divides by N−1 (Bessel's correction) to reduce bias when estimating from a sample.
- What is CV? — Coefficient of Variation — standard deviation divided by the mean, expressed as a percentage. It measures relative dispersion regardless of units.
