Answer to Question 1

ANS: A
Equivalence focuses on comparing measurement made by two or more observers measuring the same event and is referred to as interrater reliability.
Homogeneity means a likeness of subjects on identified variables.
Internal consistency relates to items being consistent within a scale.
Stability means that the same instrument will perform the same over time.

Answer to Question 2

ANS: D
Validity cannot be considered apart from reliability. If a measurement method does not have acceptable reliability (e.g., dependability, consistency, and accuracy), validity is a moot issue.
The concepts of reliability and validity go hand in hand. Validity cannot be considered apart from reliability. If a measurement method does not have acceptable reliability (e.g., dependability, consistency, and accuracy), validity is a moot issue.
A measure can be reliable, but not valid. Example: a blood pressure cuff can consistently (reliability) measure 10 mm Hg too high (not valid).
The concepts of reliability and validity go hand in hand. Validity cannot be considered apart from reliability. If a measurement method does not have acceptable reliability (e.g., dependability, consistency, and accuracy), validity is a moot issue.
