Welcome to Practical Stats
Statistical training for the environmental sciences and natural resources. From Beijing to Kansas City, our courses have enabled scientists to build better regression models, test for trends, see multivariate patterns, and correctly interpret nondetect (censored) data.

We've provided statistical training for the environmental sciences and natural resources since 1990 in the United States, Europe, China and the Middle East. We hold Ph.D.'s in statistics and environmental science, but clearly communicate information to the working scientist. We make statistics current, accurate, and practical.

In addition to our public courses announced here, we hold onsite courses directly for agencies and companies. To inquire about holding a course (typically 20 or more students) at your location, email us.
