I am in agreement with Dennis and Don. I think that students need to know both approaches since they will encounter both in the literature. Additionally, my impression is that the general goals of NHST are easier to understand when you can compare and contrast them against an ES/CI approach.

Okay, I beg your indulgence and participation in an unscientific poll where you can either post your response to the TiPS list (for discussion) or email your response directly to me. I am finishing a book review on an undergraduate statistics textbook that (a) attempts to eliminate all null hypothesis signitifcance testing (NHST) in favor of focusing on effect sizes (ES), confidence intervals (CI), and (old fashioned) meta-analysis and (b) encourages research on "statistical cognition" which, according to the author, shows that teaching NHST causes greater confusion in students than an ES/CI approach . Given that limited description, I'm going to make this into a 2-alternative forced choice question: Would you use such a textbook as the main textbook in the first/introductory statistics in psychology course? [ [ Yes [ ] No Comments? If you care to, you might comment on whether current intro stat textbooks do an adequate job of covering issues such as effect sizes and confidence intervals (these days I use some version of Gravetter and Wallnau which, in my opinion, do an adequate job introducing the topics which I assume lay the foundation for a more advanced undergraduate course in statistical methods). Thanks in advance for your cooperation. -Mike Palij New York University [email protected] P.S. And, no, this not about procrastinating on finishing the book review. Well, mostly it's not. ;-)
