The four levels of measurement are nominal, ordinal, interval, and ratio. Nominal measures classify elements into categories of a variable that are exhaustive and mutually exclusive, and represent characteristics or attributes of a variable. They are the lowest level of measurements. There is no rank-order relationship among categories, and the investigator cannot measure the distance between categories. When numbers are assigned to the categories, they mainly serve as codes for the purpose of data collection and analysis, but have no numerical meanings. Ordinal measures refer to those indicators or variables whose attributes may be logically rank-ordered along some progression. They may also be used to allow respondents to rank certain items in terms of their preference. Ordinal
measurement is more advanced than nominal measurement. In addition to the rank-order function, ordinal measurement contains all the characteristics of a nominal measure, including classification, exhaustiveness, and exclusiveness. Interval measures refer to those variables whose attributes are not only rank-ordered but are separated by equal distances. Interval measures are more advanced than either nominal or ordinal measures and contain all the properties of the others. Interval measures do not have a true zero, and zero is merely arbitrary. Because of this arbitrary-zero condition, there are very few interval measures in health services research. Very often, interval measures are mixed together with ratio measures, called interval-ratio measures, and the arbitrary-zero requirement is ignored. Ratio measures are similar to interval measures, except that ratio measures are based on a nonarbitrary or true zero point. The true-zero property of ratio measures makes it possible to divide and multiply numbers meaningfully and thereby form ratios. Like interval measures, ratio measures are a higher level of measurement than nominal and ordinal measures, and contain all their properties. What will be an ideal response?
