Definitions for "Interval scale"
a scale of measurement that indicates the exact magnitude of scores, but not their ratio to one another. (641)
A measuring system having the property that intervals between the numbers assigned accurately reflect intervals between the magnitudes of the objects being measured. The important implication is that a given difference between two scores is independent of location along the scale.
A measurement scale that measures quantitative differences between values of a variable, with equal distances between the values.
