Kate received a z score of 1 on a reading test. What do we know about Kate's performance, assuming that the reading test scores are distributed normally?a. She scored better than 84% of other students.b. She scored better than only 2/3 of the other students.c. She scored worse than only 2/3 of other students.d. She scored worse than 84% of other students.
If a person's true score is 110 on a test with a standard error of measurement of 3.7 and a mean of 100, we would expect 95% of the person's test scores to fall withina) 102.75 - 117.25b) 92.75 - 107.25c) 90.75 - 120.25d) 100-110
The standard error of measurement is a function of which two factors?a) reliability of the test and range of test scoresb) variability of test scores and range of test scoresc) reliability of the test and variability of test scoresd) variability of test scores and sample size
What is the equivalent T score for an IQ score of 115?
Which source of error variance affects parallel- or alternate-form reliability estimates but does not affect test-retest estimates?a. fatigueb. learningc. practiced. item sampling
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 bea) lower than the original reliability coefficientb) reliability would not change, but validity would increasec) higher than the original reliability coefficientd) none of the above
Which best conveys the meaning of an inter-scorer reliability estimate of .90?a. Ninety percent of the scores obtained are reliable.b. Ninety percent of the variance in the scores assigned by the scorers was attributed to true differences and 10% to error.c. Ten percent of the variance in the scores assigned by the scorers was attributed to true differences and 90% to error.d. Ten percent of the test's items are in need of revision according to the majority of the test's users.
