Module overview
The goal of this module is for you to understand what statistical tests do and do not show, what
p-values mean, and to be able to conduct a simple statistical test (the t-test). By the end of the
module, hopefully you will be able to do the following things:
- Explain what populations, samples, and inferential statistics are;
- Explain what a p-value does and does not mean;
- Recognize which situations a t-test can be used for;
- Recognize when to use an independent or dependent t-test;
- (advanced) Carry out t-tests on real data and make conclusions from the results.
