Constructing your measurement theory
A good measurement theory provides a coherent framework that links your construct(s) to observable data.
- [Classical test theory]
- [Modern test theory]
Aligning your measurement theory with your measurement design
Even the most rigorous theoretical framework fails if it is not supported by a design that can validly and reliably capture the intended constructs.
Validating your measurement theory
It is important to evaluate whether the assumptions of your measurement theory hold in practice.
