Example:

Developing a new psychological test to measure anxiety requires the application of statistical methods to ensure its reliability and validity.

Implications:

This field is crucial for ensuring that psychological research adheres to rigorous methodological standards, and it has substantial applications in psychometrics, health outcomes research, and policy formulation.
