Kuder-Richardson Formula

The Kuder-Richardson Formula is a statistical method used to measure the reliability of tests or questionnaires, particularly those with multiple-choice questions. It assesses how consistently a test measures what it aims to evaluate, such as general knowledge. A higher score from this formula indicates that the questions yield similar results across different respondents, suggesting that the test is reliable and valid. Essentially, it helps determine whether a set of items effectively gauges the knowledge or skill it is intended to measure, ensuring trust in the test results.
