Answer to Question 1

ANS: C

Feedback
A This answer does not reflect validity, but rather it reflects characteristics of screening tests.
B Validity does not guarantee minimal random errors.
C Validity of an instrument is associated with its accuracy.
D Interrater reliability is not an example of validity.

Answer to Question 2

ANS: C

Feedback
A When the error variance is low, the reliability coefficient will be closer to 1; a reliability level of 0.70 or higher is considered acceptable.
B When the error variance is low, the reliability coefficient will be closer to 1; a reliability level of 0.70 or higher is considered acceptable.
C When the error variance is low, the reliability coefficient will be closer to 1; a reliability level of 0.70 or higher is considered acceptable.
D When the error variance is low, the reliability coefficient will be closer to 1; a reliability level of 0.70 or higher is considered acceptable.
