 Statistics Learning Centre Videos. Short videos on a range of statistical topics. I've only viewed a couple (one on confidence intervals, and one on hypothesis testing), and thought the material was explained very clearly. Unfortunately, the video on hypothesis testing directed viewers to use Excel to perform the analysis. Using Excel for serious statistical analysis is not recommended. See the following pages, for example.
 Statistics FAQ from the MRC Cognition and Brain Sciences Unit. (Several of the items address questions about SPSS.)

 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.

 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.

"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).
