Discussion
Appraise and debate the sampling methods and determine the quality of the sampling procedures in reducing bias. Consider the following questions:Was the sampling method and inclusion/exclusion criteria adequate to reduce sampling bias?Are the sample characteristics representative of the target population?Was the sample size adequate?Was there a decrease in sample size? If so, did the researchers identify decreases early and attempt to reduce the impact? Was a decrease, if any, adequately explained by the researchers?
