Ordinal dates. Ordinal data is a type of categorical statistic in which variables are ordered according to natural categories and the distances between categories are unknown.
What is the difference between ordinal and nominal data?
Nominal data includes naming or identifying data, since the nominal word has a Latin root with the word name and has a similar sound, the function of nominal data is easy to remember. Ordinal data contains order information, and ordinal numbers and order are the same, which also makes it easy to remember the function of ordinal data.
What is the difference between ordinal and categorical data?
Ordinal data and variables are considered intermediate levels between categorical and quantitative variables. In other words, ordinal data is categorical data for which the values are ordered. Compared to nominal data, the latter are categorical data whose values cannot be ordered.
