Ordinal data is a categorical, statistical data type where the variables have natural, ordered categories and the distances between the categories is not known.: 2 These data exist on an ordinal scale, one of four levels of measurement described by S. S. Stevens in 1946. For example, the ranges of income are considered ordinal data while the income itself is the ratio data. Unlike interval or ratio data, ordinal data cannot be manipulated using mathematical operators. Due to this reason, the only available measure of central tendency for datasets that contain ordinal data is the median. If we need to define ordinal data, we should tell that ordinal number shows where a number is in order.

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). 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.

2. Treat ordinal variables as numeric. Because the ordering of the categories often is central to the research question, many data analysts do the opposite: ignore the fact that the ordinal variable really isn’t numerical and treat the numerals that designate each category as actual numbers. Status at workplace, tournament team rankings, order of product quality, and order of agreement or satisfaction are some of the most common examples of the ordinal Scale. These scales are generally used in market research to gather and evaluate relative feedback about product satisfaction, changing perceptions with product upgrades, etc. 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

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.
