Leading scholars in psychology and other disciplines are striving to help scientists enhance the way they conduct, analyze, and report their research. They advocate the use of “the new statistics,”— effect sizes, confidence intervals, and meta-analysis. APS’ flagship journal, Psychological Science, has been inviting authors to use the “new statistics” as part of a comprehensive effort to enhance research methodology.

In this workshop, Geoff Cumming, a leading expert in new statistics, explains why all these changes are necessary, and suggests how psychological scientists can implement them. The workshop was recorded at the 2014 APS Annual Convention in San Francisco, and is presented here as six video segments. It makes extensive use of interactive simulations to illustrate concepts, and provides a wealth of practical guidance.

Part 1 Includes:
• An introduction to estimation based on confidence intervals

• Problems with NHSTand the advantages of estimation

• Cognitive evidence to guide choice of statistical techniques

• Some problems with p values

• The ‘dance of the p values’.
