Cathy is seven years old. At her annual checkup, her doctor says her height is in the 50th percentile among children her age. What type of norm does this describe?
Explanation
Answer: A - Age norms, also called age-equivalent scores, indicate the average score of test takers at different chronological ages. In this example, Cathy’s height will grow as she ages but her age equivalent score may or may not change. Age norms that refer to physical characteristics, such as height and weight, are largely non-controversial. However, age norms that measure psychological attributes such as intelligence are used less frequently now than in the past.
