Rasch Analysis

Rasch Analysis is a statistical method used to measure and evaluate the quality of survey or test data, ensuring that questions or items accurately reflect a specific ability or trait. It transforms raw survey scores into a common scale, allowing for fair comparisons across different groups or tests. By analyzing patterns of responses, Rasch Analysis identifies which items are most effective and whether the test is reliable. This helps developers create fair, consistent, and meaningful assessments or questionnaires in fields like education, psychology, and healthcare.
