What Is Non Parametric Test Example
Whilst the trimmed mean performs well relative to the mean in this example better robust estimates are available. For example to use this data analysis tool for Example 2 press Ctrl-m and choose T Tests and Non-parametric Equivalents from the menu that is displayed or from the Misc tab if using the Multipage user interface.

The Kruskal Willis test is the non parametric alternative to the One way ANOVA and the Mann Whitney is the non parametric alternative to the two sample t test.
What is non parametric test example. Wilcoxon Signed Rank Test PRO. The main nonparametric tests are. Choosing the right test to compare measurements is a bit tricky as you must choose between two families of tests.
Data should be distributed symmetrically about the median. However this is somewhat parametric so it depends on your reasoning for wanting a non-parametric test. The only non parametric test you are likely to come across in elementary stats is the chi-square test.
Many -statistical test are based upon the assumption that the data are sampled from a Gaussian distribution. The test determines whether the median of the sample is equal to some specified value. However there are several others.
The One-Sample Wilcoxon Signed Rank Test is a nonparametric alternative to a one-sample t-test. Robust statistical methods of which the trimmed mean is a simple example seek to outperform classical statistical methods in the presence of outliers or more generally when underlying parametric assumptions are not quite correct. Your choice should be guided by what you believe is the reason for the unequal variances.
These tests are referred to as parametric tests.
