Which scenario best illustrates using a formal instrument?

• A. Administering an unstandardized interview.
• B. Observing behavior in a naturalistic setting.
• C. Administering a standardized, norm-referenced test.
• D. Asking open-ended questions informally.

Answer: (C)

A formal instrument is a tool that uses standardized procedures and fixed scoring to produce scores that can be compared to normative data. This ensures consistency across examiners and contexts and provides objective interpretation through established reliability and validity. Administering a standardized, norm-referenced test fits this idea perfectly. It comes with precise administration instructions, a uniform set of items, and a defined scoring system. The results are interpreted against norms from a representative group, allowing meaningful comparisons and clear benchmarks. The other scenarios involve less structure. An unstandardized interview lacks a uniform script and scoring method, so it doesn’t function as a formal instrument. Observing behavior in a naturalistic setting is informative but not standardized or norm-based, so it doesn’t provide the kind of objective, comparable data a formal instrument offers. Asking open-ended questions informally also lacks standardization and normative interpretation, making it unsuitable as a formal instrument. So, the scenario that best illustrates using a formal instrument is administering a standardized, norm-referenced test.
