## Test Bank For Principles And Applications of Assessment in Counseling 5th Edition by Susan C. Whiston

Multiple Choice

1. With a reliability coefficient of .81, using classical test theory we would interpret that the:​

a. ​amount of error variance to observed variance is 81 percent.

b. ​amount of true variance to observed variance is 81 percent.

c. ​instrument has good enough reliability.

d. ​instrument’s validity coefficient would be 0.812.

2. If we interpreted a reliability coefficient to indicate that 80% of the variance was true variance to observed variance, what would be the ratio of error variance to observed variance?​

a. ​0.20

b. 0.40​

c. 0.60​

d. ​0.80

3. According to classical test theory, if the observed variance of a test is 50 and the true variance is 40, what is the estimated reliability of the test?​

a. ​0.40

b. 0.50​

c. 0.80​

d. ​0.90

4. Systematic error (as compared to unsystematic error):​

a. ​significantly lowers the reliability of an instrument.

b. insignificantly lowers the reliability of an instrument.​

c. increases the reliability of an instrument.​

d. has no effect on the reliability of an instrument.​

5. What statistical technique is often used to calculate an estimate of reliability?​

a. ​Regression

b. Analysis of variance​

c. ​Factor analysis

d. ​Correlation

6. A correlation coefficient is an indicator of:​

a. ​the validity of an assessment.

b. ​the variability of the obtained scores.

c. ​the relationship between two sets of data.

d. ​the fluctuation of an individual’s score over time.

7. Correlation coefficients range from:​

a. ​-1.0 to 1.0.

b. 0 to 1.0.​

c. 0 to -1.0.​

d. -5.0 to 5.0.​

8. When calculating correlations, the most common method used is the:​

a. ​Pearson-Product Moment Correlation Coefficient.

b. Correlation Coefficient of Most Common Factors.​

c. Reliability Coefficient of Correlation.​

d. Reliability Correlation Coefficient.​

9. The statistic that represents the percentage of shared variance between two variables is the:​

a. ​correlation coefficient.

b. reliability correlation.​

c. ​coefficient of determination.

d. ​coefficient of shared variance.

10. For which of the following tests would a test-retest reliability estimate be least appropriate?​

a. ​Intelligence tests

b. Tests of moment-to-moment mood changes​

d. ​Instruments to measure art aptitude

11. Which of the following is NOT one of the assumptions that should be met when establishing the reliability of an instrument using the test-retest method?​

a. ​Test-retest reliability is only valid when measuring situational traits

b. The characteristic or trait measured should be stable over time​

c. ​There should be no differential in practice effect

d. ​There should be no differential in learning between the test and retest

12. The most significant difficulty with estimating reliability with the alternate or parallel forms procedure is​

a. ​calculating the correlation coefficient using two different forms.

b. ​the effects of remembering specific items in the second testing.

c. developing two sound instruments that are equivalent or parallel.​

d. ​finding two similar sets of test takers.

13. The Spearman-Brown formula is used:​

a. ​to correct a test-retest reliability coefficient.

b. to correct a split-half reliability coefficient.​

c. when the items are all of the same difficulty level.​

d. ​when the items are of differing levels of difficulty.

14. The decision to use either the Kuder-Richardson 20 (KR 20) or the Kuder-Richardson 21 (KR 21) is based on whether:​

a. ​the method used to determine reliability is the test-retest or the alternate form method.

b. correlation or regression is going to be used.​

c. the items measure a homogeneous or heterogeneous behavior domain.​

d. the item format is multiple-choice or true-false.​

15. What is the most appropriate way to determine reliability with Likert scales, where different answers receive different weightings?​

a. ​Test-retest

b. Spearman-Brown​

c. Kuder-Richardson 20​

d. Coefficient alpha (or Cronbach’s Alpha)​
