13 ## T-tests
14 You learned the theory/concepts behind t-tests last week, so here's a brief run-down on how to use built-in functions in R to conduct them and interpret the results.

16 ## ANOVAs

18 Analogous situation with t-tests. Here's a brief introduction to how they work in R.

20 ## Visualizing confidence intervals
21
22 We spent a lot of time on confidence intervals in the past few weeks. Since they can be so useful, surely we should learn some approaches to incorporating them into data visualizations.

24 ## Date/time arithmetic
25
26 Last, but not least, another wrinkle in time...or at least how to manage date-time objects in R.
