What is happening cognitively when we do scaling? In this module, we will review what scaling is, the purpose, and methods of scaling. We’ll wrap up this module with a discussion on the different types of scales, including ordinal scales, quantitative scales, interval scales, and analysis. Let’s begin.

In this module, we will continue our discussion on scales and measurements. We will also discuss methods of scaling and ranking and review other types of scales, such as Hedonic scales, Label Affective Magnitude, Just-About-Right, and other scales of interest. Let's begin.

Why do some people perform better on tests than others? In this final module, we will end our discussion with an overview of discrimination testing methods. We'll also take a closer look at discrimination tests and response bias - and how to avoid it. We'll move on to Thurstonian Modeling and finish up with an optional podcast conversation with Lori Rothman. Let's begin.
