The independent samples t test can be used to compare means for just two groups (and this is sometimes also reported as a follow up to a statistically significant ANOVA).... Reasons to Use Parametric Tests. Reason 1: Parametric tests can perform well with skewed and nonnormal distributions. This may be a surprise but parametric tests can perform well with continuous data that are nonnormal if you satisfy the sample size guidelines in the table below.
