Chapter 3: levels of measurement and scaling chapter objectives structure of the chapter levels of measurement nominal, ordinal, interval and ratio and so the treatment given to them here will be brief that is there is no information about the interval between any two brands all of the information a nominal scale would have given is. Types of data & measurement scales: nominal, ordinal, interval and ratio research writing no notes for slide measurement scales 1 nominal, ordinal, interval and ratio research writing 2 4 measurement scales (or types of data) • nominal, ordinal, interval and ratio • they are simply ways to categorize different types of variables.
In nominal scale, it is easy to generate responses using close ended questions, a lot of responses can be collected in short period of time, which in turn increases reliability however, there is a downside to the scale, without a linear scale, participants are unable to express their degrees of response.
Nominal, ordinal, interval, and ratio typologies are misleading paul f velleman, cornell university and data description, inc nominal, ordinal, interval, and ratio typologies are misleading paul velleman and leland wilkinson 1 introduction nominal scales are at the other end of the hierarchy they do not even require the assignment. A physical example of a nominal scale is the terms we use for colours the underlying spectrum is ordered but the names are nominal in research activities a yes/no scale is nominal.
Four types of measurement scales nominal ordinal interval ratio • the scales are distinguished on the relationships assumed to exist between objects having different scale values • the four scale types are ordered in that all later measurement and measurement scales author. Level of measurement or scale of measure is a classification that describes the nature of information within the values assigned to variables psychologist stanley smith stevens developed the best-known classification with four levels, or scales, of measurement: nominal , ordinal , interval , and ratio.
The scoring varies greatly from a simple nominal scale (right/wrong) to detailed 22- and 31-point scoring (table 1 [4-6, 9-19]) the clock-drawing test for example, user help can be measured on a nominal scale , having two groups: online or hard copy.
This classification system categorizes the variables as being measured on either a nominal, ordinal, interval, or ratio scale after introducing the classification system and providing examples of variables which are typically measured on each type of scale, we note the implications of these measurement scales for the analysis of data.
