It is shown that, for kernel-based classification with univariate distributions and two populations, optimal bandwidth choice has a dichotomous character. If the two densities cross at just one point, where their curvatures have the same signs, then minimum Bayes risk is achieved using bandwidths which are an order of magnitude larger than those which minimize pointwise estimation error. On the...

Multiple-choice testing with dichotomous scoring is one of the most common assessment methods utilized in undergraduate education. Determining students’ perceptions toward different types multiple-choice formats important for effective assessment. The present study compared two alternative used a second-year required chemistry course: (1) Immediate Feedback Assessment Technique (IFAT®) and (2) ...
