Final answer:
Dr. Winston would compare his patient's resilience score to a normative group to understand how the patient's resilience compares to others in the same age group, using the established norms as a comparative benchmark. Hence, option (c) is correct.
Step-by-step explanation:
Dr. Winston would compare his patient's score to scores for a normative group. In the field of psychology and psychometrics, a normative group consists of a sample of individuals who represent a larger population, such as a certain age group, within which we can expect a distribution of various scores on a given measure. The purpose of a normative comparison group is to provide a benchmark against which individual scores can be evaluated to determine where an individual stands in relation to the typical performance within that group.
For a test to be normed and standardized, it is essential that it is administered to a representative sample which could include same-age peers. This process helps ensure more accurate and consistent scoring, and interpretation of individual scores since the norms reflect the actual performance of the group rather than an expectation of knowledge or ability.
Thus, for Dr. Winston's patient, comparing the resilience score to normative data allows an understanding of how the patient's resilience stands relative to others in the same age group, providing critical context for the assessment.
