In order to hear the voice-overs on the powerpoints, you will have to download them onto your own computer.
In order to follow along with the exercises you will have to download R and R Studio. You can find a document "Installing R" in the Module 1 Component on this OSF page that will explain how to do that.
You can find the Example Data Set that is used throughout the course in the Example Data Set component.
I have also added a component that contains my R script that you can use after you have completed all of the exercises to see whether you have done them correctly, or that you can use whenever you cannot make your code work.
