Inferential statistical analyses that are based on a set of assumptions about the underlying population are called parametric tests. These tests assume a normal distribution of the population and equal variances between groups. If these assumptions are not met, the results of the test may not be accurate. However, if the assumptions are met, parametric tests are the most powerful and precise type of statistical analysis.
