There is no particular answer to this question, using parametric or non-parametric analysis depends on the questions and details of your research design. Non-parametric tests are not assumption free. Their assumptions are dependent on the context. On the other hand, Non-parametric tests have a broad class of models available. It deals with different types and distributions.
