So what have you learned? You've learned the
differences between P values and confidence
intervals, and you've learned about the null
hypothesis, three foundational ideas in statistics.
You've also learned the difference between
data and information, and you realize that
without context the numbers mean nothing.
The human component is everything, it is not
simply about crunching numbers, it’s about
interpreting numbers and adding value and
meaning via your own expertise and perspective.
You’ve also learned the differences between
different types of variables, continuous versus
discrete, dichotomous variables and multi-categorical
variables, all of which will help make you a
much better epidemiologist and clinical researcher.
