January 2016 Member Webinar: Analysis of Ordinal Variables–Options Beyond Nonparametrics

by Karen Grace-Martin

There are many types and examples of ordinal variables: percentiles, ranks, likert scale items, to name a few.

These are especially hard to know how to analyze–some people treat them as numerical, others emphatically say not to.  Everyone agrees nonparametric tests work, but these are limited to testing only simple hypotheses and designs.  So what do you do if you want to test something more elaborate?

In this webinar we’re going to lay out all the options and when each is reasonable.  There are more options than most people realize.

We’ll discuss the advantages and disadvantages of each one and what assumptions you’re really making when you pick one.


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