Building measures from raw scores - we need to use the Wright stuff!

Research output: Contribution to journal › Article

Abstract

This is a short exercise designed to get people thinking about the difference between counting and measuring. This exercise utilizes the fact that balloons are highly similar manufactured products. But they can be manipulated by the trainer in terms of their number, size and color. Helium filled balloons are also easy to obtain and visually engaging. They are large enough for students to see in any classroom. This presentation is dedicated to Dr. Benjamin D. Wright - psychological measurement hero! It starts with the replication of some famous graphs by Dr. Wright (Wright 1993, Wright 1997).
