nonparametric
No distribution assumed
Nonparametric describes statistical methods that don't assume data follows a specific distribution like a normal curve.
These techniques work with ranked data or make minimal assumptions about underlying patterns: nonparametric tests, nonparametric regression.
Useful when sample sizes are small or data violates assumptions required by traditional methods.
