Environmental Sampling Theory
Study Design, Data Collection, and the Appropriate Use of Statistics in Data Reporting (Course I.D. STAT-403)
Hosted by Northwest Environmental Training Center

This course provides an overview that will cover the basic terms, concepts, and logic that underlie modern scientific sampling. Much of the class will be devoted to the understanding of how to apply the basic concepts of probability to sampling problems and how to use probability theory to design an appropriate sampling protocol and measure its effectiveness. We will compare the difference between purposive and random sampling and discuss why random sampling (and its many variations) is so frequently used in manufacturing, science, and government. This class will emphasize written communication, in the style of a scientific report, as an essential part of the scientific sampling process. The course is intended for environmental professionals who have had a limited statistical background, who hope to plan small-scale sampling studies, or who use sampling results to make management recommendations. This is not a course about number crunching, nor a class on sample size determination. This is a brief introduction to the theory and practice of scientific sampling.

Registration: $495 (*$395 reduced tuition available for Native American tribes; government employees; nonprofits; students; and NAEP, NEBC, NWAEP members). You may register via the link below or by calling the Northwest Environmental Training Center at 206-762-1976.
