This assignment is a critical evaluation of research conducted by others; it is not an opinion piece. You will need to synthesize what you have learned so far this semester (study designs, interpretation of relative risk, odds ratios, data tables, etc), information learned from other classes in your course of study (history, geography, psychology, sociology), and apply critical analysis to a journal article. At a minimum, I would recommend 10 hours of effort to receive an adequate grade. As for this assignment range from four to eight pages of Word document on average (depending on how succinct your writing is) before being pasted into the assessment. Be detailed, be thorough; if you paste directly from the article, you will receive a 0 for the question. This single assignment is worth 100 points and translates to 12.5% of your final grade. Both assignments combined therefore are worth 25% of your final grade and are weighted in the gradebook accordingly.I suggest you do this assignment in a word processing document beforehand.
