Overview of Content
If you already know this material, there is no need to access the instructional content. Evaluate your knowledge by taking the first quiz from the link on this page, and, if successful, fill out the form and move on to the next module.
Content
The pdf's contain all the material in written form presented in each section. The optional videos cover the same material with additional verbal explanation. If you are comfortable with your understanding of the pdfs, there is no need to watch the videos.
For purposes of this pre-course, you can ignore all references to computer commands, which are minimal but covered in the actual course. You can skip references to the computer in the pdfs/videos where it occurs. The focus for the pre-course is limited to basic statistical concepts such as a histogram, standard deviation, etc.
The pdfs are updated on a regular, ongoing basis. The videos are updated less frequently. So if there are any minor differences between the two presentations, the pdfs are more current.
