How do we classify variables?
Classifying variables can be somewhat contentious. Standard statistical textbooks will state that variables can be broadly classified as categorical or continuous. Categorical variables can be further categorised into nominal (e.g. ethnic group), ordinal (e.g. tumour staging) and dichotomous (e.g. sex).
