How is an interval variable similar to an ordinal variable?
An interval variable is similar to an ordinal variable, except that the intervals between the values of the numerical variable are equally spaced. For example, suppose you have a variable such as annual income that is measured in dollars, and we have three people who make $ 10,000, $ 15,000 and $ 20,000.
How is the interval scale a quantitative scale?
