Examples of Using R for Modeling Ordinal Data Alan Agresti Department of Statistics, University of Florida Supplement for the book Analysis of Ordinal Categorical Data, 2nd ed., 2010 (Wiley), abbreviated below as OrdCDA c Alan Agresti, 2011 Examples of methods (non- parametric) properly used for ordinal data were Mann– Whitney U-test, Kruskal–Wallis test, Wilcoxon’s signed rank test and Spearman’s rank correlation. 2021-03-12 · Examples of ordinal data Some examples of ordinal data include: Academic grades (A, B, C, and so on) Happiness on a scale of 1-10 (this is what’s known as a Likert scale) With the Wilcoxon one sample test, you test whether your ordinal data fits an hypothetical distribution you’d expect. In this example we’ll examine the diamonds data set included in the ggplot2 library. We’ll test a hypothesis that the diamond cut quality is centered around the middle value of “Very Good” (our null hypothesis). This involves, for example, finding the central tendency (what most respondents believe) and the spread / dispersion of the responses (how strongly respondents agree with each other).

Ordinal data are always placed into some kind of hierarchy or order (hence the name ‘ordinal’—a good tip for remembering what makes it unique!) While ordinal data are always ranked, the values do not have an even distribution. The nominal data just name a thing without applying it to an order.

This involves, for example, finding the central tendency (what most respondents believe) and the spread / dispersion of the responses (how strongly respondents agree with each other). Because Likert scales produce what are called ordinal data, I suggest that you calculate the median and Inter-Quartile Range (IQR) of each item. Ordinal scales give great data about the request for decisions, for example, in a consumer loyalty review. Interim scales give us the request for values + the capacity to evaluate the contrast between each one At long last, Ratio scales give us a definitive request, interim qualities, in addition to the capacity to compute proportions since a “genuine zero” can be characterized.
