October 15, 2020: Noon – 2 pm ET
(17-19:00 London Time)
Website: https://www.niss.org/events/statistics-debate
(Online webinar debate, free but must register to attend on website above)
Debate Host: Dan Jeske (University of California, Riverside)
Participants:
Jim Berger (Duke University)
Deborah Mayo (Virginia Tech)
David Trafimow (New Mexico State University)
Where do you stand?
- Given the issues surrounding the misuses and abuse of p-values, do you think p-values should be used?
- Do you think the use of estimation and confidence intervals eliminates the need for hypothesis tests?
- Bayes Factors – are you for or against?
- How should we address the reproducibility crisis?
If you are intrigued by these questions and have an interest in how these questions might be answered – one way of the other – then this is the event for you!
Want to get a sense of the thinking behind the practicality (or not) of various statistical approaches? Interested in hearing both sides of the story – during the same session!?
This event will be held in a debate type of format. The participants will be given selected questions ahead of time, so they have a chance to think about their responses, but this is intended to be much less of a presentation and more of a give and take between the debaters.
So – let’s have fun with this! The best way to find out what happens is to register and attend!
