Quizplus · Accepted Answer

Item characteristic curves are a key part of quantitative item analysis, as they allow researchers to graphically represent how well individual test items discriminate between high and low performers. A is incorrect, as constructing a group discussion agenda would not typically be considered part of quantitative item analysis. B is incorrect, as one-on-one interviews are generally a qualitative research method rather than a quantitative one. D is incorrect, as numerical rating scales are not specific to item analysis and could be used in a variety of research contexts.
