Main Results:

Related Experiment Videos

  • Measurement theory is defined as the systematic thought process and knowledge base for valid measurements.
  • Applying measurement theory to behaviors enhances the integrity and relevance of tests and data.
  • Scalable and detectable events must be translated into pertinent, valid, and reliable measurements for useful data.

Conclusions:

  • Valid measurements are essential for the usefulness and truthfulness of all assessments.
  • Adherence to measurement theory ensures the reliability and relevance of scientific data.
  • The rules for assigning numbers to events are the core of measurement theory.
