Post by: xoxolove on Mar 8, 2018 ANS: B The area under the receiver operating characteristic (ROC) curve is the most important overall measure of classifier performance. ANS: C Knowledge discovery and data mining (KDDM) makes use of specialized analytic methods, characteristically machine learning, to identify patterns in a semi-automated fashion. ANS: A, B, C, D, F The knowledge transformation process in the STAR Model occurs at five points, which can be conceptualized as a five-point star. These five points include discovery research, evidence summary, translation to guidelines, practice integration, and evaluation of process and outcomes. Testing the hypothesis is not a specific point in the STAR Model. ANS: A, B, C, D Standardized terminology is requisite for naming, classifying, tagging, and locating evidence in order to use it in practice. ANS: A, B, C Evidence summaries include evidence synthesis, systematic reviews, integrative reviews, and reviews of the literature.
