parametric test

par·a·met·ric test

a statistical test that depends on an assumption about the distribution of the data, for example, that the data are normally distributed.

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.

parametric test

A test or trial that depends on the assumption that the date involved are normally distributed.

Just as a researcher must be cautious regarding the violation of assumptions when computing a parametric test statistic, one must recognize that effect size measures are also sensitive to violations of assumptions--specifically, non-normality and heterogeneity (Leech & Onwuegbuzie, 2002).
