1. Sample size is ≤ 30. "The parametric assumption of normality is particularly worrisome for small sample sizes (n < 30). Nonparametric tests are often a good option for these data" (Hoskins, 2018). 2. The non parametric test is more simplistic compared to the parametric test, and "less affected by outliers" (Changing Minds, 2018). Overall, its best to use parametric testing when the data given is linear, and normally distributed based on the mean and standard deviation, fitting within the parameters of the parametric tests. It is best to use non parametric testing when the data given is non linear, abnormally distributed based on the median, and does not fit within the parameters of the parametric tests.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
