Recent updates
March 19: The workshop dates are now firm. The 2-day workshop in Seward AK will be held on Monday May 10 and Tuesday May 11 2004. The workshop schedule has been filled in based on those dates.
General information
I have run workshops similar to this over a decade and a half. Locations have included British Columbia, Massachusetts, Indonesia, the Philippines, New Brunswick, Alberta, Bermuda, Singapore and Malaysia (twice each at the last 5 places). Local organizers/sponsors have included BC Environment, Battelle, UNESCO, Bermuda Biological Station, Huntsman Marine Laboratory, University of Calgary, University of Western Ontario, National University of Singapore, and University Science Malaysia.
It is assumed that participants will have taken an introductory statistics course (e.g. a semester course) or have the equivalent knowledge. The workshop is sponsored by the Alaska SeaLife Center and the Prince William Sound Regional Citizens Advisory Council. It is intended for those who want to apply design principles and statistical analysis methodology to environmental studies i.e. baseline, impact or monitoring studies. The workshop fee is not yet set but it should be around $200 for non-SeaLife Center participants.
The workshop will be over the two consecutive days Mon May 10 and Tue May 11. Statistical analyses will be demonstrated throughout the workshop, using an LCD projector. Accommodation for the night of Mon May 10 in Seward can be arranged for participants who do not live in or near Seward. Please register and make other arrangements with Lea Paddock, the local organizer (see link on menu - click on "Go back to menu" button)
Workshop venue
The workshop will be held at the Alaska SeaLife Center in Seward or elsewhere in Seward as arranged by the SeaLife Center.

(The latest crazes in statistical analysis of biological community data. The offspring of a mating between a Dutch school and the Cornell school. Trendy methods such as Canonical Correspondence Analysis plus coverage of traditional methods such as Principal Components Analysis and analysis of spatial pattern. Cajo ter Braak wrote a statistical package called CANOCO that does most of it. If you are interested in analysis of community data, do not begin with this one. Read Pielou 1984 or Manly 1994 first.) Keough, M.J., and B.D. Mapstone. 1995. Protocols for designing marine ecological monitoring programs associated with BEK mills. Report No. 11. CSIRO, Canberra. (It’s a book-size report.

If you write to CSIRO in Canberra they’ll probably mail you a copy for free.) Kirk, R.E. 1982. Experimental design: procedures for the behavioral sciences. Brooks/Cole, Monterey, California. (Another good reference on experimental and observational study design. His fans, who tend to be fanatics, always ask "But what does Captain Kirk say?" (apologies to Trekkies). One of his cleverer efforts is to show how to do "pseudo-F tests" by constructing composite error terms. SAS will sometimes do this for complex designs without being asked. See Winer 1971 or Underwood 1997 for a more classical treatment of the subject.) Legendre, L., and P. Legendre. 1983. Numerical ecology. Elsevier, Amsterdam. (Very thorough text/reference.

Chapman and Hall, London. (Most texts and statistical packages limit "linear models" to ones with normally distributed error, such as ANOVA and ordinary least squares regression. Be sure you're on top of those sorts of linear models first, then look at how this book brings ”other-than-normal error distribution” models such as probit analysis, log- linear analysis of contingency tables, logistic models, and proportional hazards models for survival data, underneath the "linear models" umbrella. The statistical package GLIM implements these methods. GLIM repels many people with its different philosophy and strange syntax, but it is worth knowing how to use. See Crawley 1993.) Pielou, E.C. 1984. The interpretation of ecological data. Wiley, N.Y. (The subtitle is "A primer on classification and ordination". It's a good introduction to descriptive multivariate statistics applied to ecology. There are clear worked examples. Another good one is Manly 1994.) Pimentel, R.A. 1978. Morphometrics: The multivariate analysis of biological data. Kendall/Hunt, Dubuque, Iowa. (A good introduction to multivariate statistics. Measurements on painted turtles feature a lot in his examples, hence the title. Lots of errata but good value nonetheless.) Popper, K. 1980. The logic of scientific discovery, 10th Ed. Hutchinson, London. (It is the statement of what the philosophy of science is, what the scientific method is. For expression of this philosophy in ecological study design and statistical analysis see Underwood 1997. Popper is worth reading and understanding because this sense of “what science is” is currently under attack by Bayesian “risk analysis” types, e.g. Suter 1993, Suter 1996 Human and Ecological Risk Assessment 2: 331-347, and Stewart-Oaten in Schmitt and Osenberg 1996 in Detecting Ecological Impacts: Concepts and Applications in Coastal Habitats, Schmitt and Osenberg, eds., p. 17-27, Academic, New York. See Dennis 1996 Ecol. Appl. 6: 1095-1103, for a good response i.e. a critique of Bayesians in ecology.) Ripley, B.D. 1981. Spatial statistics. Wiley, New York. (As the preface says, "This is a guide to the analysis of spatial data". Relevant topics are spatial autocorrelation and how to deal with it, and testing hypotheses about spatial patterns of organisms. See also chapter 7 of Jongman et al. 1987.) Schmitt, R.J., and C.W. Osenberg. 1996. Detecting ecological impacts caused by human activities. Academic Press, New York. (It’s a mixed bag, with chapters by various people. But the people are mostly very good - e.g. Stewart-Oaten, Underwood, Keough, Jones & Kaly, Mapstone, Kingsford - and the topics are mostly very current and important. I totally disagree with some of it, but that’s OK - some of the chapter authors disagree with other chapter authors within the book.) Schneider, D.C. 1994. Quantitative ecology: spatial and temporal scaling. Academic Press, San Diego. (Nice coverage of how temporal and spatial scales of observations, and of what is being observed, influences results and interpretations of studies.) Seber, G.A.F. 1984. Multivariate observations. Wiley, New York. (A "bible" for multivariate statistics, including the math theory and algorithms that underlie it.) Snedecor, G.W., and W.G. Cochran. 1989. Statistical methods, 8th ed. Iowa State Univ. Press, Ames, Iowa. (Perhaps the best biologically oriented statistics text. See Zar 1996 for a more introductory level text.) Suter, G. W. 1993. Ecological risk assessment. Lewis, Boca Raton, Florida. (See also Suter 1996 Human and Ecological Risk Assessment 2: 331-347. He advocates a Bayesian-style “risk analysis”approach to environmental management decision-making, as opposed to the traditional Popperian scientific method approach. Also see Stewart-Oaten in Schmitt and Osenberg 1996 in Detecting Ecological Impacts: Concepts and Applications in Coastal Habitats, Schmitt and Osenberg, eds., p. 17-27, Academic, New York. I’m not a fan, but it’s currently fashionable scientifically and politically. For an antidote see Popper 1980, Underwood 1997, and Dennis 1996 Ecol. Appl. 6: 1095-1103. The last is a short and easy read.) Underwood, A.J. 1997. Experiments in ecology: their logical design and interpretation using analysis of variance. Cambridge Univ. Press.

Prentice-Hall, Englewood Cliffs, N.J. (Introductory biostatistics, and a well-done job.

Its main theme is that the Exxon-funded study design whatever the intentions were and whatever their design’s other virtues, was bound to have low power to detect impacts by the oilspill on the biological community. And it did, in comparison with the government-funded & supervised studies. Mind you, I was Chair of the Statistical Working Group for the latter and Peterson was Chief Scientist, so we can’t claim to be disinterested.) Stewart-Oaten, A. 1996.

(Roughly bashed together during a sabbatical period I spent at UBC, then finished by back-and-forth fax and email. Walters and I come from opposite philosophical directions re. estimation vs. testing, and Bayesian vs. Fisherian. This paper is an attempt to reconcile these philosophically different approaches in ecological applications.)
Statistical analysis software
I will mostly use Minitab Release 13 for Windows to demonstrate statistical analyses. Please note that you can download a demo from their website. Minitab has made available to me a "timed" copy of Minitab Release 13 which I will bring to the workshop for installing in participants' computers (if they bring their own computers). These copies will expire shortly after the workshop and you'll have to buy one then if you want to keep using it. I will probably also demonstrate some other statistical software for particular kinds of analysis, for example Glim (for linear models where the response doesn't need to be normally distributed or additively related to the predictors, e.g. probit, logistic and loglinear models), and RT (randomization tests of hypotheses).
