What is the main purpose of normative data in performance testing?

• A. To define universal capabilities
• B. To benchmark individual performance against a reference population
• C. To eliminate the need for individualized testing
• D. To determine salaries and promotions

Answer: (B)

Normative data provides a benchmark by collecting performance from a representative reference group. This lets you see where an individual stands in comparison to others, using measures like percentile ranks or standard scores. The main idea is to interpret a single score in the context of how the broader population performed, not in isolation. This helps determine whether someone is below, at, or above typical performance levels and track progress over time relative to peers. It also supports standardization so scores are comparable across tests and populations. The other options don’t fit as the main purpose: normative data isn’t about defining universal abilities—it's about relative standing within a group. It doesn’t replace individualized testing, since decisions often need personal context beyond norms. And while norms can inform HR decisions, their primary role is benchmarking performance against a reference population, not directly setting salaries or promotions.
