Answer to Question 1

ANS: D
Observation allows for direct visualization of behaviors or events.
It is almost impossible to eliminate all distortion or bias with observational methods. Observation allows for direct visualization of behaviors or events.
Although this may be true, it is not an advantage to quality research. Observation allows for direct visualization of behaviors or events.
Subjectivity does not add credibility. Observation allows for direct visualization of behaviors or events.

Answer to Question 2

ANS: B
Observation allows for direct visualization of behaviors or events. The use of the other measures is inappropriate for this population because infants cannot think critically or articulate their experiences.
Interviews are not appropriate for this study example.
A semantic differential scale would not be appropriate for the study example.
A visual analogue scale is not appropriate for this study example.
