Given that the assumption of normality is violated, a typical paired t-test in this situation would at best lack sensitivity, and at worst provide spurious estimates. If we cannot be sure that the intervals between each of these five values are the same, then we would not be able to say that this is an interval variable, but we would say that it is an ordinal variable.

Descriptive statistics for ordinal data. The following descriptive statistics can be used to summarize your ordinal data: Frequency distribution The mode and/or the median; The range; Frequency distribution describes, usually in table format, how your ordinal data are distributed, with values expressed as either a count or a percentage. Let Ordinal data kicks things up a notch. It’s the same as nominal data in that it’s looking at categories, but unlike nominal data, there is also a meaningful order or rank between the options. Here are some examples of ordinal data: Income level (e.g. low income, middle income, high income) Highlighted the descriptive statistics you can obtain using ordinal data: Frequency distribution, measures of central tendency (the mode and median), and variability (the range). Introduced some non-parametric statistical tests for analyzing ordinal data, e.g.

One of the most notable features of ordinal data is that the differences between the data values cannot be determined or are meaningless. Generally, the data categories lack the width representing the equal increments of the underlying attribute. You can use these descriptive statistics with ordinal data: the frequency distribution in numbers or percentages, the mode or the median to find the central tendency, the range to indicate the variability. Ordinal data is a categorical, statistical data type where the variables have natural, ordered categories and the distances between the categories is not known.

Ordinal data is data which is placed into some kind of order by their position on the scale. For example, they may indicate superiority. Because this is ordinal data, the assumptions that the data follow a normal distribution will be violated. Given that the assumption of normality is violated, a typical paired t-test in this situation would at best lack sensitivity, and at worst provide spurious estimates.
