- 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.)

This is an introductory-level statistics book. The material is
presented both as a standard textbook and as a multimedia presentation.
The book features interactive demonstrations and simulations, case
studies, and an analysis lab.
- Notes for Research Methods and Statistics PESS202, from the School of Psychology, University of New England.

Topics include: Exploratory analysis, regression, distributions, sampling distributions, one sample, two samples, and re-sampling.
- Biostatistics links from GraphPad.com:
- Carl Schwarz's homepage.
Carl is from the Department of Statistics and Actuarial Science at
Simon Fraser University in BC, Canada. His page has links to some great
resources for statistics students, including course notes and practice questions. Stat-201 (formerly called Stat-301) may be of most interest to students in introductory stats classes.

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 Gal-Chen, 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 non-linear 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).
