Given this situation, what could you say about the tool? A. The tool has low validity, moderate reliability and high utility B. The tool has high validity, low reliability and moderate utility C. The tool has high validity, high reliability and low utility D. The tool has low validity, high reliability and low utility Two common ways to increase a test’s reliability is to: A. Lengthen the test item and/or decrease the number of test items B. Reduce the number of people in the normative sample and/or use another criteria C. Increase the number of perfectly correlated items and/or reduce the number of people in the normative sample D. Remove the items with low reliabilities and/or add more items According to the method proposed by C.H. Lawshe, you achieve a zero CVR for a particular item when: A. More experts rate the item not essential B. More experts rate the item essential C. Exactly half the experts rate the item essential D. There is no such thing as a zero CVR 10.
