Answer to Question 1

ANS: B
Research allows for data that can be interpreted and generalized to be collected systematically. Generalization extends the implications of study findings from a research sample to a larger population. Evaluation is generally limited in scope to a single situation or group.
Research studies cannot control for all extraneous variables.
Prediction is not the goal of all research.
Objectivity should be maintained in both instances.

Answer to Question 2

ANS: A
Clinical significance is related to the practical importance of findings, whereas statistical significance addresses the mathematical findings following statistical analysis of data.
The finding may or may not have general significance.
Further testing would be required before any inferences could be made.
No mathematical significance means no statistical significance.
