What is the difference between normative data and percentile bands?

• A. Normative data refer to reference data from a population; percentile bands categorize performance into ranges.
• B. Normative data are measured from the individual; percentile bands show consistency.
• C. Normative data are for elite athletes only; percentile bands apply to beginners.
• D. Normative data are always from current season; percentile bands are historical.

Answer: (A)

Normative data are reference values gathered from a population to establish what’s typical or expected for a given group (often broken down by factors like age, sex, or sport). They let you compare an individual's score to a larger standard. Percentile bands are ways to express where a specific score falls within that distribution. They divide the population into ranges (percentiles), so you can say a person is, for example, in the 60th percentile or within a particular band like the 50th–75th percentile. So, normative data provide the benchmark from a population, while percentile bands translate an individual’s standing within that benchmark into a rank-based range. The other options describe characteristics that don’t match how normative data and percentile bands are defined or used.
