Exams of a secondary service course on Statistics at University, covering t-tests, linear regression, 1- and 2-way ANOVA, and non-parametric tests, contained two parts: one with open-ended questions and one with multiple-choice questions, each with 45 credits max. We have student scores (per item) of approximately 4000 first attempts for 12 different exams, some of which are used several (≤ 4) times. Main question is whether we could use multiple-choice questions only in our exams. Besides showing some descriptive statistics for the two parts, and analyses of the relationship between scores for the two parts, we will present results of a series of factor analyses to identify whether the items in the two sets represent different latent traits.
