Test Score Variability

Test score variability refers to the differences in scores that individuals receive on a general knowledge test. It reflects how much scores differ from each other; higher variability indicates a wider range of scores, while lower variability suggests scores are more similar. Factors influencing variability can include differences in knowledge levels, test difficulty, and even testing conditions. Understanding this variability helps educators assess the effectiveness of curricula and identify areas where students might need additional support or enrichment to improve their general knowledge.
