what is data? what is its relation to reality?
levels and units of analysis
types of variables
determining -- causal, interactive, confounding
questions to address
(and dummy tables)
You need to decide:
Coverage: how many people?
Content: what activities (components)?
Specify … keep going till you answer them … refer back to them when you get lost
(tables, models, graphics)
Work up dataset
How serious/extensive is it? (Compare to norms)
Is it worse in some places/for some populations? (Compare between groups at one time)
Is it getting better or worse, for whom? (Compare between times, for groups: norm 0.5 – 1 ppt/yr)
What is cause of current situation, or changes? (Analyze associations; includes evaluation)
You could also ask: what problems are we trying to solve, and what resources do we have … this would come in at question 1, but then continue to ask how the resources address the problems ...
