This 4.5-day course covers applied statistical methods tailored to the environmental sciences. The course develops hands-on expertise for all environmental scientists who interpret data and present their findings to others. A complete understanding of how statistical methods work unfolds through applications to field-oriented problems in water quality, air quality and bio contaminants. Statistical methods are explained in the light of data with nondetects, outliers and skewed distributions. Methods for estimation and prediction are illustrated along with their common pitfalls. Emphases include nonparametric methods, including permutation tests and bootstrapping. The course doubles as an introduction to using the free R software.

Topics include:

  • Trend analysis -- is it getting better or worse?
  • Confidence, prediction and tolerance intervals.
  • How hypothesis tests work.
  • Parametric, nonparametric and permutation tests. When to use which.
  • How to build a good regression equation.
  • Dealing with outliers.
  • When are transformations OK?
  • How many samples do I need?

...and more.
