Glossary - interval scale

Indexinterval scale

An interval scale is one whereby we have a well-defined ratio of intervals, but have no absolute zero point on the scale, so that we cannot speak of something being 'twice as large'. Operations on interval values include testing for equivalence, greater and less than, and for a known ratio. (See measurement scales.)
