Quizplus · Accepted Answer

Parametric statistics require interval or ratio data because they assume a normal distribution and use mathematical formulas that require numerical values. Nominal or ordinal data do not meet this criteria and are better suited for nonparametric statistics. The size of the sample may also be important, but it is not a defining characteristic of parametric statistics._qualitative data can be converted to numerical values and used in parametric statistics if they meet the assumptions.
