Which single value is used to summarize a distribution of scores, often represented by the mean?

• A. Central Tendency
• B. Assessment
• C. Anecdotal Record
• D. Cloze

Answer: (A)

Think about how you summarize a whole set of scores with one number. That idea is called central tendency. It’s about the point that best represents where most scores cluster in a distribution. The mean is a common way to express this, because it uses every score in the set to find a balance point, giving a precise single value that reflects the overall level of performance. The other terms don’t serve as that kind of single numeric summary: assessment is the process of measuring or evaluating, not a single value; an anecdotal record is a narrative note about a student’s behavior or performance; a cloze is a reading activity where words are omitted to test comprehension. So central tendency is the concept describing a single value that represents the distribution, with the mean as a typical example.
