validity and reliability

Validity and reliability are essential concepts in assessing general knowledge. **Validity** refers to whether a test or measure actually assesses what it claims to measure; for example, does a quiz on geography truly evaluate geographical knowledge? **Reliability**, on the other hand, refers to the consistency of the results; if the same person takes the quiz multiple times, do they get similar scores? High validity ensures that the test targets the right content, while high reliability ensures dependable results, both crucial for accurately understanding and evaluating one's general knowledge.
