Answer to Question 1
Ans: B
An experimental design can yield data on whether a program has produced the desired outcomes when compared with the absence of such a program or, alternatively, whether one program strategy has produced better results with regard to the desired outcomes than some other strategy. However, the experimental design is not useful for evaluation of program progress or program cost efficiency.
Answer to Question 2
Ans: D
Surveys can be very valuable in answering questions of relevance, or the need for proposed or existing programs, especially if the perceptions of clients, providers, and management are solicited. Cost efficiency, effectiveness, and outcome are difficult to measure using a survey.
