Answer to Question 2

B, C, D
Feedback:
Systematic reviews often involve statistical integration of findings through meta-analysis, a procedure whose advantages include objectivity and enhanced power. The steps in both quantitative and qualitative integration are similar and involve the following: formulating the problem, designing the study (including establishing sampling criteria), searching the literature for a sample of primary studies but not obtaining the original data set from primary study researchers, evaluating study quality, extracting and encoding data for analysis, analyzing the data, and reporting the findings.
