•Summarize the methods used to identify the sample and recruit participants into the study.
•Compare the study sample to the population. Evaluate whether or not the study sample accurately reflects the population.
•Assess whether or not the study findings can be reliably generalized to the population based on the sampling methods.
•Propose one additional strategy that could have been used in the study to effectively sample the population to ensure the study results are generalizable to the population.
The assignment must be four to five pages in length, excluding the title and reference pages, and formatted according to APA guidelines as outlined in the Ashford Writing Center. Use at least two scholarly sources, in addition to the workbook article, to support your discussion.
