Interval : A scale which represents quantity and has equal units but for which zero represents simply an additional point of measurement is an interval scale. The Fahrenheit scale is a clear example of the interval scale of measurement.
What are the 4 types of measurement scales?
Psychologist Stanley Stevens developed the four common scales of measurement: nominal, ordinal, interval and ratio . Each scale of measurement has properties that determine how to properly analyse the data. The properties evaluated are identity, magnitude, equal intervals and a minimum value of zero.
Which type of measurement scale is characterized by equal units of measurement?
The interval or cardinal scale has equal units of measurement, thus making it possible to interpret not only the order of scale scores but also the distance between them. However, it must be recognised that the zero point on an interval scale is arbitrary and is not a true zero.
What is ordinal scale of measurement?
Ordinal scale is the 2nd level of measurement that reports the ranking and ordering of the data without actually establishing the degree of variation between them. Ordinal level of measurement is the second of the four measurement scales. ... It can be named, grouped and also ranked.

This form of scale does not require the use of numeric values or categories ranked by class, but simply unique identifiers to label each distinct category. ... The nominal scale holds two additional properties.
Is a type of scale that does not use units of measurement?
Answer: The ordinal scale is based on rankings. The order matters, but the differences between the variables do not. In the case of ordinal scales, we can use a median, but never use the mean because it is meaningless.

An ordinal scale is a scale (of measurement) that uses labels to classify cases (measurements) into ordered classes. ... Some examples of variables that use ordinal scales would be movie ratings , political affiliation, military rank, etc. Example. One example of an ordinal scale could be “movie ratings”.
What are the four data measurement scales explain with examples?
Data can be classified as being on one of four scales : nominal, ordinal, interval or ratio. Each level of measurement has some important properties that are useful to know. For example , only the ratio scale has meaningful zeros. A pie chart displays groups of nominal variables (i.e. categories).
What is an example of ordinal measurement?
Examples of ordinal variables include: socio economic status (“low income”,”middle income”,”high income”), education level (“high school”,”BS”,”MS”,”PhD”), income level (“less than 50K”, “50K-100K”, “over 100K”), satisfaction rating (“extremely dislike”, “dislike”, “neutral”, “like”, “extremely like”).
Is birth year nominal or ordinal?
This scale enables us to order the items of interest using ordinal numbers. Thereof, is age nominal or ordinal? Year of birth is interval level of measurement ; age is ratio.
Is weight nominal or ordinal?
4. Nominal Ordinal Interval Ratio. Weight is measured on the ratio scale.
What is nominal scale and example?
A nominal scale is a scale (of measurement) that uses labels to classify cases (measurements) into classes. ... One example of a nominal scale could be “sex” . For example, students in a class would fall into two possible classes, male or female.
Is marital status nominal or ordinal?
Hence marital status is a nominal categorical variable . On the other hand, when the categories are naturally ordered, as with education level, socioeconomic status, or evaluation on a scale ranging from strongly disagree to strongly agree, then the variable is an ordinal categorical variable.
