5 Types of Variables for the Mean

In this video, we explore which types of variables are suitable for calculating the mean. We begin with a quick recap of how to calculate a sample mean using a simple data set. Then, we define and differentiate between interval, ordinal, and categorical variables, providing clear examples for each. We examine why the mean cannot be calculated for categorical and ordinal variables, highlighting the arbitrary nature of their numerical coding. Finally, we confirm that only interval variables are appropriate for mean calculations. Subscribe to @AxiomTutoringCourses for more educational content.
