Non-parametric does not make any assumptions and measures the central tendency with the median value. Some examples of non-parametric tests include Mann … WebWe feel that this is a reasonable expectation given that this is the largest cohort that has been interrogated with α-synuclein SAA. Second, non-parametric methods were used to compare α-synuclein SAA status in participants with Parkinson's disease for some outcomes because of the skewness of the data and the low number of samples in some groups.

Most nonparametric tests use some way of ranking the measurements and testing for weirdness of the distribution. Typically, a parametric test is preferred because it has better ability to distinguish between the two arms.

The term "nonparametric statistics" has been imprecisely defined in the following two ways, among others: 1.
