What is the difference between categorical data and numerical data?
Qualitative or categorical data have no logical order, and can’t be translated into a numerical value. Quantitative or numerical data are numbers, and that way they ‘impose’ an order. Examples are age, height, weight.
What is the difference between categorical ordinal and numerical variables?

What’s the difference between categorical and ordinal data?
Ordinal data are often treated as categorical, where the groups are ordered when graphs and charts are made. However, unlike categorical data, the numbers do have mathematical meaning.
Which is the best example of categorical data?
The data fall into categories, but the numbers placed on the categories have meaning. For example, rating a restaurant on a scale from 0 (lowest) to 4 (highest) stars gives ordinal data. Ordinal data are often treated as categorical, where the groups are ordered when graphs and charts are made.
Do you use nominal ordinal or interval data?
Some techniques work with categorical data (i.e. nominal or ordinal data), while others work with numerical data (i.e. interval or ratio data) – and some work with a mix. While statistical software like SPSS or R might “let” you run the test with the wrong type of data, your results will be flawed at best, and meaningless at worst.
What’s the difference between nominal and categorical data?
