Statistics Study Guide (Henry Gersh & Habiba Emadi Keshtiar). Your opinion?

Well I think by now every credible form of life on this planet is aware of the very helpful Statistics Study Guide (Introduction to Statistics) by Henry Gersh and Habiba Emadi Keshtiar. However I would like to check out some other study guides so I can do a comparison. The stats course I am currently studying uses SPSS . Thank you all for your time and patience.
