Question

Quizplus · Accepted Answer

A nominal scale is used for labeling variables and does not have any quantitative value or order. It only serves as a means of identification and classification of the objects, without any underlying relationship between the labels themselves. Therefore, it fits the description given in the question. The other options like ratio, ordinal, and interval scales involve some level of quantitative measurement or relationship between their numbers, and hence they would not be appropriate. Random scale is not a recognized term in statistics.
