Think you know stats? Stuart Hurlbert first described pseudoreplication—a common but serious statistical error—in 1984. Despite widespread knowledge of the error, pseudoreplication is often misinterpreted, and literature surveys show that the error is on the rise in certain fields. Listen to Hurlbert define pseudoreplication and other related errors, plus hear why we shouldn’t dichotomize results as “significant” and “non-significant,” what’s missing from basics stats courses, and what’s next on his list.
Join us as we speak with Dr. David Barton, Guest Editor of the special series “Bayesian Networks in Environmental and Resource Management,” to discuss the basics of Bayesian approaches in environmental management. The series is composed of seven case study articles, each of which applies the Bayesian network approach to environmental and resource management problems around the world. Access the series in the July 2012 issue of IEAM.
Drs. Landis and Chapman are authors of an editorial in the October 2011 issue of IEAM entitled, “Well Past Time to Stop Using NOELs and LOELs.” The editorial was essentially a call to end the use of these two measures in favor of more statistically robust approaches. Join us as we hear more from Wayne and Peter on their call to move away from relying solely on hypothesis testing.
