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.

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.

A Quick Quiz; As you might know, there are 4 measurement scales: nominal, ordinal, interval, and ratio. Knowing the measurement level of your data helps you to interpret and manipulate data in the right way. Let’s define the interval data: Can I do a paired samples t-test when my data are ordinal? My data are reading levels at time 1 and time 2, but the data levels are A, 1 2,3,4,6,8,10, 12, 14, 20, 24, 28, 30, 34, 38, 40, 50, 60, 70, 80.

Due to this reason, the only available measure of central tendency for datasets that contain ordinal data is the median. Inferential statistics try to make inferences from the data: what does the data tell us about what is not in the data?

For example, they may indicate superiority.

The data collected by this survey are examples of ordinal data. Here the numbers assigned have an order or rank; that is, a ranking of "4” is better than a ranking of “2.” However, even though you have assigned a number to your opinion, this number is not a quantitative measure: Although a ranking of “4” is clearly better than a ranking of “2,” it is not necessarily twice as good.
