Handouts

We’re not going to cover all the material in these handouts, but I thought you might find them useful for reference (or if you want to go further):

1. Introduction to R
2. Data wrangling
3. Data visualization
4. Basic confidence intervals and hypothesis tests
5. Linear regression with R

I’ll let you know what sections are relevant to our workshop as we go along.
