Rasch Measurement Theory

Rasch Measurement Theory is a statistical approach used to create precise, reliable assessments of abilities or traits. It works by analyzing how individual responses to questions relate to an underlying skill or characteristic, ensuring that the questions measure consistently across different people. This method transforms raw scores into a common, meaningful scale, making it easier to compare results fairly. It’s widely used in fields like education and healthcare to develop questionnaires and tests that accurately reflect what they intend to measure, helping professionals make informed decisions based on dependable data.
