Write that term in the space provided. 1. If we want to measure the proportion of health workers who acquire Ebola from working with Ebola patients, we would want to measure the incidence rate. 2. A(n) percentile indicates the percent of the population that falls below a certain value. 3. A(n) reliability index , for a particular data point, represents the distance from the mean in terms of standard deviations. 4. ANOVA is used to determine if three or more sample means are statistically not all equal. 5. Norm-referenced test is a test that compares an individual to other individuals. 6. Criterion-referenced tests compares an individual to certain defined standards. 7. A(n) observed score is the score actually achieved by an individual on a test. 8. A(n) standard score is the average score an individual would achieve if he or she were to take the test infinite times. 9. In Classic Test Theory, random measurement error can eventually be eliminated over time as the number of tests increases. 10. Systematic measurement error occurs when something that is entirely unrelated to the test is affecting test scores.11. Item Response Theory takes into account that different questions may have different levels of difficulty. 1 12. A(n) true score measures how well a person's observed score on a test represents that person's true score. 13. In the test-retest method the same test is given to the same sample on two different occasions. 14. Two versions of a test are given at the same time to each of half of a sample of students. This is an example of the parallel-forms method. 15. Item analysis is the study of the results of each individual question on a test. Analysis of Learning Objectives True or False [Show More]
