Answer to Question 1

ANS: D
Observation tends to be more subjective than other types of measurement, and this is often considered less credible.
It is quite difficult to control observational methods, although it is a goal. Observation tends to be more subjective than other types of measurement, and this is often considered less credible.
Observation allows for some flexibility in data collection. Observation tends to be more subjective than other types of measurement, and this is often considered less credible.
Observation tends to be unstructured and more subjective than other types of measurement, and this is often considered less credible.

Answer to Question 2

ANS: B
Because validity reflects the extent to which a measurement instrument actually measures the construct or concept being measured, a research consumer should look closely at the measurement tool to ensure that what was being measured in the study is valid.
Validity would not be determined from additional data analysis.
Although this is important, it would not provide validity for the study findings.
The research purpose would not provide evidence of validity.
