Interval measure is defined as a level of measurement describing a variable whose attributes are rankordered and have equal distances between adjacent attributes. The Fahrenheit temperature scale is an example of this, because the distance between 17 and 18 is the same as that between 89 and 90. Please see nominal measure, ordinal measure, and ratio measure.
Interval method is a term in behavioral observation, a technique for converting observations into numerical scores that involves dividing the observation period into a series of intervals and then recording whether or not a specific behavior occurs during each interval.
