Types of Variables and Measurement and Accuracy Scales
Abstract
This chapter highlights the importance of defining variable measurement scales to develop researches, and to treat and analyze data. The differences between metric or quantitative variables, and nonmetric or qualitative variables are established, as well as the circumstances in which each type of variable must be used, based on the research objectives. For each type of variable, we must use the most suitable statistical treatment.
