A categorical variable, which is also referred to as a nominal variable, is a type of variable that can have two or more groups, or categories, that can be assigned. There is no order to the categories that a variable can be assigned to. In other words, the categories cannot be put ...
What is a Variable? The definition of a variable changes depending on the context. Typically, a letter represents them, and it stands in for a numerical value. In algebra, a variable represents an unknown value that you need to find. For mathematical functions and equations, you input their ...
