Welcome to Module 4.
This module will follow the same format
as the previous two and that will review
some topics from Epi 1 and then take a deeper dive.
This module focuses on measures of association,
things like risk ratio, attributable risk,
and odds ratios.
We'll review when it is appropriate
to use each type of measure.
And then we'll look more deeply
into the mathematical development
and relationship between the measures,
particularly the relationship between risk and odds.
This will be important as we move forward.
If these measures have been tricky for you in the past
or if you're just feeling like it's been a while
since you've thought about them,
I'd encourage you to start
by going back to your Epi 1 textbook and notes
before you dive into this week's content.
