Instructor Resource Furr, Psychometrics, 4e SAGE Publishing, 2022 Chapter 3: Differences, Consistency, and the Meaning of Test Scores Test Bank Multiple Choice 1. A group of respondents took a psychological test. In their distribution of test scores, the variance is 4.56. Which of the following is the most accurate statement about that value? a. It means that the people’s scores on the test are likely connected to scores on another test b. It reflects a small amount of variability (people did not differ greatly from each other, in terms of their test scores) c. It reflects a large amount of variability (i.e., people do differ quite a lot from each other, in terms of their test scores) d. This value is possible, but it is difficult to know whether it reflects a large or small amount of variability.
