Welcome to Practical Stats

Statistical training and consulting for the environmental sciences and natural resources. From Singapore to South Dakota, our courses have enabled scientists to build better regression models, test for trends, see multivariate patterns, and correctly interpret nondetect (censored) data.

Training Courses
We provide online on-demand courses, as well as on-site training for agencies and companies. We also regularly present webinars on a variety of topics related to environmental statistics. See our Training Page for registration and course details. To inquire about holding a course (typically 20 or more students) at your location, email us.

Recordings of past webinars are available on our Online Training Center.
"Fitting Distributions to Data with Nondetects", our Feb 19, 2019 webinar, is now available for free viewing on our Online Training Site. See our Webinars Page for other available webinars.

We work with business and government agencies to analyze data, write guidance or technical reports, and work alongside your employees to upgrade their knowledge of applied statistics. See our Consulting page for more information.

We've provided statistical training for the environmental sciences and natural resources since 1990 in the United States, Europe, Asia 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.
