Match the following descriptions of Hill's Criteria to their names:
I. The condition can be altered, either prevented or accelerated
II. Observation of association must be repeatable in different populations at different times
III. Cause/exposure must precede the effect/outcome
IV. The association should be compatible with existing theory and knowledge, including knowledge of past cases and epidemiological studies
V. A single cause produces a specific effect
VI. Relationship is clear and risk estimate is high
VII. The association agrees with currently accepted understanding of
VIII. Consideration of multiple hypotheses before making a conclusion about whether an association is causal or not
IX. An increasing amount of exposure increases the risk

1. Alternative Explanations
2. Coherence
3. Temporality
4. Biological Plausibility
5. Specificity
6. Strength of Association
7. Experimental Evidence
8. Dose-Response Relationship
9. Consistency
List in order the ten steps in an epidemiological investigation.
Easy questions.

I'm going to do Question 1 and 2.
1. VIII
2. IV
3. III
4. VII
5. V
6. VI
7. I
8. IX
9. II
Also, for Biological Plausibility, you forgot to add, "biological and pathological processes." btw I knew that because I have the exact definitions in my cheat sheet i swear i didnt look it up :oops:
1.Prepare team and resources
2. Establish existence of outbreak
3. Verify the diagnosis
4. Construct case defintion
5. Find cases systemically and develop line listing
6. Performing descriptive epidemiology/perform additional studies as necessary
7. Develop hypotheses 
8. Implement control measures
9. Communicate findings
10. Maintain surveillance

All are correct. Somehow I left that part off :oops:
Here's what I have on my cheat sheet:
1. Prepare for field work
2. Establish the existence of an outbreak
3. Verify diagnosis
4. Define and identify cases
5. Describe and orient the data in terms of person, place, and time
6. Develop hypotheses
7. Evaluate hypotheses
8. Refine hypotheses
9. Control and prevention measures
10. Communicate findings
Pretty similar, but I think you added a few unnecessary steps.
Your turn.

The problem with asking this question is that both answers are right (and that all the "steps" could easily be broken down into multiple steps).

Of course, Killboe's answer leaves out actually testing the hypotheses :P

Why might you stratify a table of case-related mortalities by age?

So that you can see whether the case affects older/younger/middle aged people, and that data can help you prevent further deaths.

Age is a common confounding variable.
Your turn.
