11.A test question which everyone answers correctly a)is a poor item because any item that more than 60% of people answer correctly is too easy b)is a poor item because it has a low reliability c)is a poor item because it does not discriminate d)is NOT a poor item because it is fair to everyone 12.Test items with p values of 0.0 or 1.0 affect the _______ of a test. a)reliability b)mean c)validity d)internal consistency 13.A test with either all extremely difficult items or all extremely easy items will show ______ on individual test scores. a)little variability b)much variability c)extreme range d)large differences 14.In order to decide whether each applicant is above or below the 30th percentile, you should use a test that consists of items with p values near a)0.2 b)0.3 c)0.5 d)1.0 15.The D statistic in item analysis is a measure of a)item difficulty b)item discrimination c)item distraction d)item complexity 16.The item-total correlation is a statistic that gives information on a)item difficulty b)item discrimination c)item distraction d)item complexity 17.An item with a p value of _______ guarantees that the item will be a good discriminator. a)0.5 b)1.0 c)0.0 d)none of the above 18.The probability of choosing the correct answer to an item can be represented graphically via a)item characteristic curves b)item classification curves c)item consistency curves d)item response curves 19.When the item-total correlation is ____, the slope of the item characteristic curve is _______. a)negative; positive b)negative; negative c)positive; negative d)positive; zero 20. Item Response Theory provides measures that are a)sample specific b)sample indifferent c)sample invariant d)sample inversed 21.A test is more precise if the difficulty level of the test corresponds with each individual’s ability level. Constructing a test for each individual is a)too time consuming b)tailoring the test c)routinely done for all tests d)all of the above 22.If an Item Characteristic Curve has a steep upward slope, this indicates that a)there is a weak relationship between test scores and responses to the particular              item illustrated in the graph b)an item has negative discriminating power c)people who did well on the test are less likely to do well on this particular item d)people who did well on the test are much more likely to answer the item correctly 23.Item Response Theory does all of the following EXCEPT a) encourages you to think about why people answer items correctly b) defines difficulty in terms of the level of ability needed to answer the item                           correctly c)links item responses to total test scores rather than to the construct the test is                           designed to measure d) has become the dominant theme in modern psychometric research 24. Which approach gives you the best opportunity to obtain information by examining which incorrect response was chosen on a test? a) classical reliability theory b) true score theory c) item response theory d) response dissimulation theory
