Nominal scale: A scale used to label variables that have no quantitative values. Some examples of variables that can be measured on a nominal scale include: Gender: Male, female. Eye color: Blue, green, brown. Hair color: Blonde, black, brown, grey, other. Blood type: O-, O+, A-, A+, B-, B+, AB-, AB+.
The nominal, ordinal, interval, and ratio scales are levels of measurement in statistics. These scales are broad classifications describing the type of information recorded within the values of your variables.
A Nominal Scale is a measurement scale, in which numbers serve as “tags” or “labels” only, to identify or classify an object. This measurement normally deals only with non-numeric (quantitative) variables or where numbers have no value.
Levels of measurement, also called scales of measurement, tell you how precisely variables are recorded. In scientific research, a variable is anything that can take on different values across your data set (e.g., height or test scores). There are 4 levels of measurement: Nominal: the data can only be categorized.
Definitions for Nominal, Ordinal, and Scale. Nominal Data. Variables at the nominal level are categorical and have no inherent order or numerical meaning. Examples include gender (e.g., male or female), ethnicity (e.g., Asian, African American, Caucasian), or marital status (e.g., married, single, divorced).
A nominal scale is the 1 st level of measurement scale in which the numbers serve as “tags” or “labels” to classify or identify the objects. A nominal scale usually deals with the non-numeric variables or the numbers that do not have any value.
A nominal scale is a naming scale where variables are simply “named” or labeled with no specific order. The ordinal scale has all its variables in a specific order, beyond just naming them. Interval scale offers labels, order, as well as a specific interval between each of its variable options.
The nominal scale categorizes data without giving any quantitative value or order. The ordinal scale goes beyond categorizing data to arrange it in some order. The interval scale provides an equal distance between values, allowing for quantitative differences.
Nominal scales (also known as a categorical variable scale) refer to variables, categories, or options that don’t have a regular order or ranking that has universal application. For example, male and female are both categories but neither one can be ranked as number one or two in every situation.
