 Alan McLean's commentary on the hypothesis testing controversy. In April 2000, Alan McLean posted to one of the stats newsgroups a couple of messages concerning the hypothesis testing controversy. I find his commentary to be very sensible and refreshing, which cannot be said for much of what one reads concerning this topic.
 When does Correlation Imply Causation? Selected contributions from a discussion, on the EDSTAT list (and newsgroup sci.stat.edu), about the phrase "correlation does not imply causation". The opening post is by Dr. Karl Wuensch.
 The Analysis of Observations with Applications in Atmospheric Science. An online texbook by William A. Cooper with chapters by Thomas W. Schlatter,
Tzvi GalChen, and David B. Parsons. The primary objective of this text is to provide a broad background in the methodology of experimental research. Most areas are not covered in great depth, and it is expected that it will be necessary for readers to delve deeper into topics like spectral analysis or the techniques of fitting nonlinear parameters before these will become comfortable tools. However, the course should provide a good introduction to the range of approaches available, so that an experimenter can then pursue applicable possibilities in more depth.
 Concepts and Applications of Inferential Statistics. This is a free, fulllength, and occasionally interactive statistics textbook. It is a companion site of VassarStats, a website for statistical computation.

 Virtual Laboratories in Probability and Statistics. Webbased resources for students and teachers of probability and statistics. Looks like a nice site.
 Health Statistics Tools of the Trade. Statistical Measurements, Data Analysis, Charts and Graphs, and Data Collection/Processing.
 Statistics glossary by Valerie J. Easton and John H. McColl.

The simplest definition [of ordination] is "Putting Things in Order"; (Wartenberg et al. 1987, Peet et al. 1988, Jackson and Somers 1991, Palmer 1993). The origin of the term "ordination" in ecology is attributed to Goodall (1954).
