Member Training: Determining Levels of Measurement: What Lies Beneath the Surface

by TAF Support 

You probably learned about the four levels of measurement in your very first statistics class: nominal, ordinal, interval, and ratio.

Knowing the level of measurement of a variable is crucial when working out how to analyze the variable. Failing to correctly match the statistical method to a variable’s level of measurement leads either to nonsense or to misleading results.

But the simple framework of the four levels is too simplistic in most real-world data analysis situations.

In this training, you will learn:

  • Different ways of describing and thinking about level of measurement
  • The statistical and other practical considerations in determining a variable’s level
  • When and how we can decide to change a variable’s level

Note: This training is an exclusive benefit to members of the Statistically Speaking Membership Program and part of the Stat’s Amore Trainings Series. Each Stat’s Amore Training is approximately 90 minutes long.
