April 2019 Member Webinar: Non-Parametric Analyses

Oops—you ran the analysis you planned to run on your data, carefully chosen to answer your research question, but your residuals aren’t normally distributed.

Maybe you’ve tried transforming the outcome variable, or playing around with the independent variables, but still no dice. That’s ok, because you can always turn to a non-parametric analysis, right?

Well, sometimes.

The term “non-parametric” has come to imply that we don’t need to make any assumptions about the specific distribution of our residuals, but it certainly doesn’t mean that there are no assumptions at all.

If you are interested in learning more about appropriate occasions for non-parametric tests, how they work, and the conclusions that we can draw from them, please join us.

We will cover simple rank-based tests (such as the Mann-Whitney U test and the Wilcoxon signed rank test), as well as permutation/randomization-based tests and basic bootstrapping methods.

In this webinar you will learn:

• Appropriate uses for non-parametric tests and understanding the results
• Rank-based tests (such as the Mann-Whitney U and Wilcoxon signed rank)
• Permutation/randomization-based tests
• Basic bootstrapping methods

Note: This training webinar is an exclusive benefit to members of the Statistically Speaking Membership Program.
