Understanding The New Statistics: Effect Sizes, Confidence Intervals, and Meta-Analysis

摘要

The author is Emeritus Professor in the Department of Psychology at La Trobe University. That gives a context which explains his using the term "the new statistics" to describe the use of estimation and confidence intervals as an alternative to "null hypothesis significance testing." Some might consider both strategies as exemplifying "old statistics," and regard other areas or schools of statistics as "the new statistics," but psychologists have a long history of being focused on identifying that an effect exists, and so making heavy use of hypothesis testing procedures.
