Final answer:
Individual test scores are not compared to the scores of their normative age group when calculating FSIQ. Instead, they are compared to a representative sample of the population.
Step-by-step explanation:
False. When calculating FSIQ (Full Scale Intelligence Quotient), individual test scores are compared to the scores of a representative sample rather than just the normative age group. Norming and standardizing a test involves administering the test consistently to a large enough sample of the population to establish a range of scores that result in a bell curve. This ensures that new scores can be interpreted accurately and reliably.
