The real issue is whether arithmetic and other mathematical operations with the values makes sense. So it is a continuous variable. A continuous variable can be numeric or date/time. Even half sizes are still not really measurement but "whole number", because there is nothing between size 8 and 8 1/2. At a Glance - Qualitative v. Quantitative Data. Excellent > poor service.

In other words, the categories cannot be put in order from highest to lowest. Match. The difference is explained in the following two sections. Qualitative data are measures of 'types' and may be represented by a name, symbol, or a number code. Above mentioned types are formally known as levels of measurement, and closely related to the way the measurements are made and the scale of each measurement. Quantitative.

Consider shoe sizes, we can say that the difference in shoe size 8 and shoe size 7 is equal to the difference in sizes 2 and 3. Ratio Level: Continuous variable can theoretically take infinitely many values in a given range. Shoe sizes are, in a sense, a continuous measure - you can, in theory, make a size 11.231 shoe. But if it's not a size 13 (or close), it's not going to fit me, so it's a categorical measure for all practical purposes. Ordinal, interval and ratio scales are quantitative. Is shoe size categorical data? 4. Quantitative. Consequently, we can expect some relationship or association between these variables and shoe sizes. Categorical vs. Quantitative Data.
