What are the 4 main categories of data?

The question is about data analysis

Answer:

There are four basic types of data: Nominal, consisting of distinct, unordered categories; Ordinal, having a defined ordering but uneven intervals; Interval, having equal intervals with no true zero, like temperature; and Ratio, with equal intervals and a true zero, allowing meaningful comparisons, for instance, weight or height. These types direct the choice of statistical methods and how the data should be interpreted.
