Which term describes the dispersion, spread, or scatter of scores in a distribution?

• A. Concepts of Print
• B. Variability
• C. Validity
• D. Print Awareness

Answer: (B)

Dispersion of scores in a distribution is about how spread out the scores are. This characteristic is called variability, which captures the amount of difference among individual scores in a data set. When scores vary a lot, the distribution shows high variability; when they’re clustered around a central value, variability is low. The other terms refer to different ideas—Concepts of Print and Print Awareness relate to understanding printed text, while validity concerns whether a test measures what it’s supposed to measure. So variability is the term that describes the dispersion, spread, or scatter of scores.
