The decision to determine if a parametric or nonparametric test must be selected is important as it depends on whether the data follows a normal distribution or not. If the data follows a normal distribution, a parametric test can be used, otherwise, a nonparametric test must be chosen. This initial decision will help in selecting the appropriate test for further analysis.
