Linear equating

Linear equating is a statistical method used to compare scores from different tests that measure the same skill or knowledge. When two tests are designed differently or given at different times, their scores may not be directly comparable. Linear equating adjusts the scores so they can be understood on the same scale, using a straight-line (linear) formula based on the relationship between the scores. This helps educators and researchers interpret results consistently, ensuring that a score on one test can be meaningfully compared to a score on another, supporting fair assessment and decision-making.
