Registration for courses at our Online Training Center is now closed.
Why Online Training?
• LEARN on your own schedule in your own timezone.
• NO TRAVEL EXPENSES!
• REVIEW materials whenever you want.
• ONE-YEAR ACCESS to all materials so the instruction doesn't end when the instructor leaves on the last day.

• CONNECT with the instructor by email (anytime during the year) or on a scheduled online help session.
Our two most popular courses (who else has taken these?) taught in-person from 1990 to 2019 were:
1. Applied Environmental Statistics (sections 1 and 2)
A survey of environmental statistics, from confidence, prediction and tolerance intervals to regression models and trend tests in many varieties. Parametric, nonparametric and permutation tests.
Cost: $650/year per person for each section, or $1200/year for the entire course.

Statistical methods for data with nondetects (also called "censored data").
How to compute means, UCL95s, hypothesis tests, regression, trend analysis and multivariate methods, all without substituting one-half the DL for nondetects.

Comment from a student (State agency staff) at our 2013 Applied Environmental Statistics course:
“Thank you again for the incredible course: easily the best and most useful stats class I have taken.
Dennis Helsel (PhD in Environmental Science and Engineering, Virginia Tech) has over 40 years experience in applying statistical methods to environmental sciences. He has authored articles in numerous journals
, including papers on handling nondetect data such as “More Than Obvious” (ES&T 2005) and "Much Ado About Next to Nothing" (Ann. Occ. Hygiene, 2010). Dr. Helsel has authored Statistics for Censored Environmental Data using Minitab and R (Wiley, 2012), the textbook for interpreting data with nondetects, and co-authored Statistical Methods in Water Resources (USGS, 2nd ed. 2020)
. Dr. Helsel is the 2018 recipient of the Lifetime Acheivement Award from the California Groundwater Resources Association, and a 2003 recipient of the Distinguished Service Award from the American Statistical Association's section on Statistics and the Environment.. See our Credentials page for more information. We've been teaching courses on practical statistics to scientists since 1990.
