parametric test

A statistical test or procedure using a quantitative measure—standard error, standard deviation, mean square error of variability or spread—in the data to establish a p-value (t-tests, ANOVA). Parametric tests assume that the distribution of the observations or datapoints is known. For a parametric test to produce valid p-values, the data must have a Gaussian ("normal") distribution.
