What defines a "norm group" in testing?

• A. A group of students chosen at random
• B. A group that provides normative data for test scores
• C. A group defined by specific learning disabilities
• D. A group of students from a single school

Answer: (B)

The concept of a "norm group" in testing is pivotal in interpreting an individual’s test scores within a broader context. A norm group is essentially a representative sample of individuals who have taken a particular test, used to establish standard performance levels and norms. This group facilitates the comparison of an individual's scores against those of a larger population, providing insights into where an individual stands relative to the norm. Having a norm group allows researchers and educators to develop benchmarks, making it possible to understand the meaning of a specific score. For instance, if a student scores at the 70th percentile on a standardized test, it means they performed better than 70% of the individuals in the norm group. Thus, the essential function of a norm group is to supply the normative data that determines how test scores are interpreted, making this choice the correct response. Other contexts such as random samples, specific learning disabilities, or limited groups from a single school do not adequately define the overarching role of a norm group in standardized testing, which is to provide comparative data for a broader population, facilitating effective assessment and evaluation.
