Is anyone aware of a statistics resource (preferably 20 to 40 pages maximum) that reviews basic stats for people who took statistics classes already?
This resource could be handed out as a refresher to those who need it. The reason why I'm not looking for a book is that I find that people will more likely read a 20/40 pager than a 500 page book that goes into too much detail for the intended scope.
The ideal resource will explain the statistical methods, hypotheses, various methods, etc. It has to cover methods like Chi-squared. It has to be written in an easy to read and digest manner.
