Secondary Assessment #1

Filed in Homework

Case-control and Cohort Studies Award
‘A’ students should be able recognize and understand the benefits and limitations of interpretations from specialized (but common) study designs. They should also be able to synthesize material and suggest alternative approaches.


To gain this award, find a recent edition of an epidemiology or medical journal (within the last 12 months). Review each of the first 6 observational studies presented. Outline the study design of each study. Briefly describe the authors’ findings and conclusions, for each article. Then describe the limitations on the conclusions that are due the challenges of the general design (not the issues that are unique to that particular study). Separately and distinctly, describe the limitations due to the particulars of the study. If there are no case-control or cohort studies presented among the first six that you review, work your way sequentially through the rest of the journal until you have six in total and at least one of each type. Describe only the these six.


For three of the reported studies, suggest two alternative study designs that could be (feasibly) implemented to address the research questions presented in the papers. Explain how and why the results of your suggested designs would be an improvement, in terms of interpretation.

As part of the assessment, your instructor may question you orally about your work, after submission. Present copies of the articles as part of your submission. This is due September 18th.

OTHER AWARDS from Assessment 1
The other awards will be reassessed with an in-class assessment. This assessment will be more comprehensive of your skills than the primary. This assessment will be issued on September 18th. Please make a note of the date, and begin preparing as soon as possible. Utilize all your resources and address questions about material early. Work with your instructor on this material as early as possible.

Advisory: JMP Utilization

Filed in Announcements

1. Reminder: Where do you get the data for the examples and problems? The book comes with a disk with all the data. It is also distributed on the course website. (side note: I’m working with the publisher on the applets.)

2. Homework problems that are marked as a Four Step Problem or Large Data Set problems are possible primary assessment questions just like the rest. You should use JMP for these problems. For these particular questions you will be allowed to bring raw JMP output (without added notes) to class, to be used during the assessments. This output will be needed for some problems. The output must be yours and you must be able to recreate the output. In some cases, I will have you create the output as part of your assessment.

3. Use of mobile phones and personal computers is not allowed during primary assessments.

Anecdotes Not So Good for Ebola

Filed in In the Media

If You Have Question(s):
Before the end of the day on Sunday, submit a list of questions, concerns you’ve had about Chapter 8 and 2 material and have not been able to confidently resolve.
