The terms parametric statistics and nonparametric statistics refer to the two major groupings of statistical procedures. The major distinction between them lies in the underlying assumptions about the data to be analyzed.

When the data are interval or ratio scaled and the sample size is large, parametric statistical procedures are appropriate.
