Score for this quiz: 25 out of 25 Submitted Apr 10 at 4:27pm This attempt took 16 minutes. 1.25 / 1.25 pts Question 1 A researcher wants to measure content-sampling error and has two versions of an achievement test available. What measure of estimating reliability would be best in this situation? Alternate forms Test-retest Split-Half reliability Internal consistency reliability 1.25 / 1.25 pts Question 2 Jose has developed a test that has poor reliability; he can seek to increase reliability by: Increasing the number of test questions. Decreasing the number of test questions. Making the test questions more ambiguous. Starting over and developing a new test. 1.25 / 1.25 pts Question 3 A researcher wants to measure internal consistency in a test that measures two different constructs (self-esteem and depression) without subdividing the items into the two construct groupings. Which of the following would be the best method to use in measuring internal consistency? Split-half reliability Kuder-Richardson Formulas CoeRcient alpha Any of the above methods would be equally appropriate. 1.25 / 1.25 pts Question 4 If the reliability coeRcient of a test is determined to be .27, what percentage is attributed to random chance or error? 27% 73% 2.7% Unknown percentage 1.25 / 1.25 pts Question 5 You are attempting to account for a time sampling error and decide to administer the test a second time. In discussing reliability, you report this as what method of estimating reliability? Alternate forms Test-retest Split-half reliability Internal consistency reliability 1.25 / 1.25 pts Question 6 In reviewing a newly developed test instrument, the evaluator noticed that some of the items did not appear to reWect the construct being measured; he reported there was: Content-sampling error Time-sampling error Interrater differences error Test-taker variables error 1.25 / 1.25 pts Question 7 An administrator and the school psychologist were observing a child to assess for behavioral problems. An error may occur in reviewing what the two observers notice; this is reported as: Content-sampling error Time-sampling error Interrater differences Test-taker variables 1.25 / 1.25 pts Question 8 You are reading about reliability of a test in the test manual and notice that the researchers report using a Spearman-Brown coeRcient. You can infer that internal consistency reliability was measured using: The Kuder-Richardson Formulas CoeRcient alpha Split-half reliability Test-retest 1.25 / 1.25 pts Question 9 When interviewing test takers who had taken an achievement test on three different occasions, participants reported that they had remembered some of the answers from the previous test administration; this is known as: Practice effect Content effect Test-retest effect Carryover effect 1.25 / 1.25 pts Question 10 The SEM for an achievement test is 2.45. Johnny scores 100 and we assume that 68% of the time his true score falls between + 1 SEM; this means the con\dence interval would be between: 0 and 102.45 2.45 and 100 95.10 and 104.90 97.55 and 102.45 1.25 / 1.25 pts Question 11 _______________ is calculated by correlating test scores with the scores of tests or measures that assess the same construct. Convergent validity Discriminant validity Face validity Content validity 1.25 / 1.25 pts Question 12 A professor wants to assess students’ knowledge of material taught through lectures. However, the professor asks questions that were not discussed during class lectures. This may result in problems with _______________ validity. Construct Content Discriminate Face 1.25 / 1.25 pts Question 13 Comparing pre and post-test scores of two groups – one group that experienced an intervention and one group that did not – is an example of: Factor analysis. Contrasted group studies. Experimental results. Age differentiation studies. 1.25 / 1.25 pts Question 14 Convergent validity evidence is established by ___________ correlating instrument results with the results of other instruments that assess the same construct correlating results among four or more instruments having experts determine whether a test measures the same construct factor matrix 1.25 / 1.25 pts Question 15 A test designed for elementary school children was administered to 11th grade students. To these students, the test seemed extremely childish and inappropriate. They cooperated poorly with the testing procedure, and, as a result, this negatively impacted their outcomes on the test. Which of the following would have best addressed this problem? Evidence of homogeneity. Discriminant evidence. Evidence based on consequences of testing. Evidence based on response processes. 1.25 / 1.25 pts Question 16 The tripartite view of validity includes content validity, criterion validity, and: Discriminate validity Convergent validity Content validity Construct validity 1.25 / 1.25 pts Question 17 Exploratory factor analysis can be used to: Investigate the differences between groups. Develop new testing instruments. Con\rm expectations about a scale's dimensions. Determine if a test produces negative consequences. 1.25 / 1.25 pts Question 18 _______________ is a threat to validity that implies that a test is too narrow and fails to include important dimensions or aspects of the identi\ed construct. Content underrepresentation Content-irrelevant variance Construct underrepresentation Construct-irrelevant variance 1.25 / 1.25 pts Question 19 Validity coeRcients greater than __________ are considered in the very high range. .50 .60 .70 .80 1.25 / 1.25 pts Question 20 To evaluate a content validity evidence, test developers may use: Expert judges Factor analysis Experimental results Evidence of homogeneity Quiz Score: 25 out of 25 PREVIOUS NEXT Submission Details: Time: 16 minutes Current Score: 25 out of 25 Kept Score: 25 out of 25 Home Announcements Assignments Discussions Grades Modules Writing Style Guides Quizzes Online Residential Athletics Alumni Parents Sign In Request Info Apply Now Visit Us Create Guest Account
