Note that the nominal data examples are nouns, with no order to them while ordinal data examples come with a level of order.
What is nominal and ordinal data?
Nominal and ordinal are two of the four levels of measurement . Nominal level data can only be classified, while ordinal level data can be classified and ordered.
What is nominal level data?
In statistics, nominal data (also known as nominal scale) is a type of data that is used to label variables without providing any quantitative value . ... One of the most notable features of ordinal data
What is nominal scale with 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.
What is interval level data?
Interval data, also called an integer, is defined as a data type which is measured along a scale , in which each point is placed at equal distance from one another. Interval data always appears in the form of numbers or numerical values where the distance between the two points is standardized and equal.
What is the example of nominal?
Examples of nominal variables include: genotype, blood type, zip code, gender , race, eye color, political party.
Is birth year nominal or ordinal?
Knowing the scale of measurement for a variable is an important aspect in choosing the right statistical analysis. 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.
What is an example of ordinal data?
Ordinal data is a kind of categorical data with a set order or scale to it. For example, ordinal data is said to have been collected when a responder inputs his/her financial happiness level on a scale of 1-10 . ... An undergraduate earning $2000 monthly may be on an 8/10 scale, while a father of 3 earning $5000 rates 3/10.
Are names nominal or ordinal?
In summary, nominal variables are used to “name,” or label a series of values. Ordinal scales provide good information about the order of choices, such as in a customer satisfaction survey. Interval scales give us the order of values + the ability to quantify the difference between each one.
Is gender ordinal or nominal?
Gender is an example of a nominal measurement in which a number (e.g., 1) is used to label one gender, such as males, and a different number (e.g., 2) is used for the other gender, females. Numbers do not mean that one gender is better or worse than the other; they simply are used to classify persons.

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 is the use of nominal scale?
Nominal Scale, unlike the other scales from the Four Levels of Measurement, uses “tags” or “labels” to associate value with the rank . It differentiates items based on the categories they belong to. A nominal scale does not depend on numbers because it deals with non-numeric attributes.
What are the types of nominal scale?
- Mild.
- Moderate.
- Severe.
Is age an example of interval data?
We can first distinguish between categoric and interval-level data. Interval-level variables are continuous, meaning that each value of the variable is one increment larger than the previous and one smaller than the next value. Age, if measured in years , is a good example; each increment is one year.
How do you know if you are using interval data?
To identify whether a scale is interval or ordinal, consider whether it uses values with fixed measurement units, where the distances between any two points are of known size . For example: A pain rating scale from 0 (no pain) to 10 (worst possible pain) is interval.
What is an example of an interval scale?
Examples of interval scales include temperature scales, standardized tests, the Likert scale, and the semantic differential scale. Temperature scales including the Fahrenheit and Celsius temperature scales are examples of an interval scale. ... In contrast, the Kelvin temperature scale is based on a “true zero” point.
