Growing numbers of journals are now either strongly advising or even requiring the use of effect size statistics in the presentation of results. This workshop is constructed around a brief description and history of the major families of effect size statistics (zero order and adjusted), including rules of computation, transformation (how to you turn chi square into r or g into d), and appropriate presentation and use. The workshop will include introduction to the newer “common language” effect size statistics.


Learning Objectives

  • List reasons for use of effect size statistics.
  • Transform effect size statistics.
  • Cite appropriate use of differing effect size statistics.
