(written as Variable)Characteristics of individuals, usually quantified, such as blood pressure, age, income or region of residence, will vary and, hence, are termed 'variables'. So are other elements in a model that can vary but are not characteristics of people, such as inputs, price, GDP, or industrial concentration. Some variables are binary. Such variables usually indicate either the presence or the absence of a feature of interest (such as male or female, black or white, alive or dead).
