1.A loosely structured group of statistics that can be computed for each item in a test is              a(n) a)test analysis b)item confirmation c)test validation d)item analysis 2.The reliability coefficient tells you something about the effects of _______ on test scores, while _______ can tell you why a test is reliable. a)variability; validity coefficients b) measurement error; item analysis c)measurement error; validity coefficients d)variability; item analysis 3.If an item analysis suggests that an item in a test is poor, and if that item is removed              from the test, the reliability of the shorter test is likely to be a)lower than the original reliability coefficient b)reliability would not change, but validity would increase c)higher than the original reliability coefficient d)none of the above 4.A distractor is a)an incorrect alternative response to a test question b)a vague, yet correct alternative to a test question c)an item that serves as a filler item d)the correct response to a test item 5.Item difficulty analysis shows a)relatedness of responses on one test to other test items on the test b)how many people chose each response for an item c)how many people chose the correct response to an item d)the proportion of people who chose each response for each item 6.Suppose that for a question, 15% of people selected response “a”, 20% selected response “b”, 30% selected response “c” (which is the correct response), and 35% selected response “d”. Which item analysis data do you have for that item? a)item difficulty analysis data b)item discrimination analysis data c)item distractor analysis data d)both a and c 7.A good test item should be ______ for people who do not know the correct response. a)easy b)difficult c)logical d)impossible 8.A distractor that is chosen significantly fewer times than would be expected by chance a)lowers the difficulty of the item b)increases the difficulty of the item c)does not affect item difficulty d)reflects an item not in the content domain 9.Item difficulty refers to a)item complexity b)item obscurity c)the number of people who answer an item correctly d)all of the above 10.When everyone answers an item incorrectly the p value will be a)0.0 b)1.0 c)between 0.0 and 1.0 d)-1.0 1
