Nonparametric statistics are not generally as powerful (sensitive) as parametric statistics if the assumptions regarding the distribution are valid for the parametric test. That is, type II errors (false null hypothesis is accepted) are more likely. 14.1. Advantages of …

RPubs - Testing assumptions for the use of parametric tests
Checking the Assumptions for using Parametric Statistics. Parametric statistics are the most commonly used statistical methods in kinesiological research. For example, both the t-test and ANOVA are considered parametric statistics. Samples of data must meet three criteria before they can be analyzed using parametric methods.

In the last several decades, a confluence of work in the social sciences, philosophy, statistics, and computer science has developed a theory of causal inference using directed graphs. This theory typically rests either explicitly or implicitly on two major assumptions: ... Under some parametric assumptions, the Weak Causal Markov Assumption is ...

With parametric methods you need more assumptions like e.g., the population is normal, with NONparametric methods you need less assumptions. NONparametric methods can be applied more often and to more types of data, and tend to be easier to use. NONparametric methods waste info.

Prior to the main analyses, assumptions of parametric statistics were tested. The data on the covariate -math grades- were severely positively skewed. Therefore, an inverse transformation was performed on this variable. Scores on this transformed covariate and on the dependent variables were screened for outliers within each of the three groups ...
