✓ *typically a survey

Case control study
✓ A group that has the thing you're studying for, and a group that does
not have the thing you're studying for
✓ *uses odds ratio to measure results
odds ratio
✓ tells how much more likely people with the exposure are to have an
outcome; a higher number equals a greater risk (compared to the
group without the exposure)
cohort study
✓ no one in the study has the outcome you're looking for, but some are
exposed to what you believe to be a risk
✓ *you can examine cause/effect from this!!!
