I need comments on this article Tools: If the author suggests that there may be errors, is the tool or tools selected appropriate for the potential error being discussed? If the author found no evidence of statistical error, have all four tools been used sufficiently to make a cogent argument for the article properly representing the data. Data: Based on what we have learned in this class so far and your reading of the article, does the article properly represent the data (using section 1.6 criteria)? Analysis: Do you agree with the author's findings - whether the article appears to have errors or appears to be error free?
