Join experts Robert Calin-Jageman and Katherine Button as they discuss their work in estimation statistics and statistical power. Watch the short videos introducing this work below, then watch the webinar as they, along with moderator, eNeuro Editor-in-Chief, Christophe Bernard, answer questions about how these statistical practices apply to your own work.
This Ask an Expert event is part of SfN's Foundations of Rigorous Neuroscience Research (FRN) program, which aims to increase awareness of the sociological and cultural factors that influence rigorous research practices. Share topic ideas or your own experience with cultural barriers to rigor in an anonymous survey.
Estimation for Neuroscience
The estimation approach to inference emphasizes reporting effect sizes with expressions of uncertainty (interval estimates). This video explains the estimation approach and how it can help you avoid common analysis errors when interpreting neuroscience data.
Why Statistical Power Matters
Statistical power is fundamental to the design and conduct of neuroscience research. This video explains the importance of considering power to avoid falling into the trap of making false inferences.
