rating scale theory

Rating scale theory explores how individuals evaluate and assign numerical or categorical ratings to items, experiences, or attributes. It examines the mental processes behind choosing a rating (like 1 to 5 stars) and how consistently people do so. The theory helps identify factors such as bias, interpretation differences, and response styles that influence ratings. By understanding these elements, researchers can design better surveys, ensure more reliable data, and interpret ratings accurately. Essentially, it provides a framework for understanding the reliability and validity of subjective assessments captured through rating scales.
