Appraise and debate the sampling methods and determine the quality

 

  1. 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?
