What are the types of bariables?

Variables can be categorized into several types, primarily including quantitative and qualitative variables. Quantitative variables are numerical and can be further divided into discrete (countable values) and continuous (infinite possible values within a range). Qualitative variables, on the other hand, represent categories or attributes and can be classified as nominal (unordered categories) or ordinal (ordered categories). Understanding these types helps in selecting appropriate statistical methods for analysis.
