What are these?
A series of short videos designed to explain basic stats techniques, and how to do them in Excel, SPSS, and R.
This series was informed by several of Neil J. Salkind’s books on statistical training (Statistics for People
whoThink They Hate Statistics, Excel Statistics: A Quick Guide, and Using SPSS for Windows and Macintosh), and by the online R community. This video series was created with National Science Foundation funding, #1423004.
