Description:

This two and a half day course discusses the core elements of the EPA's first major revision to its groundwater statistical guidance in almost 20 years. Presented by the primary author of the revision, this course will showcase new features of the guidance, as well as recommended changes to current statistical practice. In addition to reviewing the design and evaluation of statistical programs for groundwater monitoring, participants will also learn the benefits of checking their assumptions in order to run the most effective statistical tests.
