D. correct! Four "Levels of Measurement" For levels of measurement, there are typically four major types that researchers must choose from: Nominal, ordinal, interval, and ratio. Nominal measures refers to variables whose attributes have only the characteristics of exhaustiveness and mutual exclusiveness. Variables with attributes we can logically rank in order are ordinal measures. Interval measure is a level of measurement describing a variable whose attriutes are rank-ordered and have equal distances between adjacent attributes. Lastly is ratio measure, a level of measurement describing a variable with attributs that have all the qualities of nominal, ordinal, and interval measures and in addition are based on a "true zero" point.
