Question

Quizplus · Accepted Answer

Nominal scales are used to categorize objects into different groups or types, based on some common attribute. They assign different values or names to each category but do not provide any information about the magnitude or order of those values. Therefore, nominal scales are suitable for identification or classification purposes, such as assigning a label to a certain species of plants or animals, or grouping data based on demographic variables like gender, ethnicity, or religion. The other types of scales - ordinal, interval, and ratio - involve increasing levels of quantification and measurement, and are used for more advanced statistical analyses.
