If a variable can take on any value between two specified values, it is called a continuous variable; otherwise, it is called a discrete variable. Some examples will clarify the difference between discrete and continuous variables.
A numerical or continuous variable (attribute) is one that may take on any value within a finite or infinite interval (e.g., height, weight, temperature, blood glucose, ...). There are two types of numerical variables, interval and ratio. An interval variable has values whose differences are interpretable, but it does not have a true zero.
