• Topic Outline: Effect Size, Sample Size, and Power (Word, PDF)
• Links:
  • Cohen 1992 Tables: https://bwgriffin.com/gsu/courses/edur9131/stat-data/Cohen-1992-sampling-tables.pdf
  • Excel Effect Size calculator: https://bwgriffin.com/gsu/courses/edur9131/stat-data/effect-size.xlsx
  • Excel Sample Size calculator: https://bwgriffin.com/gsu/courses/edur9131/stat-data/samplesizelinear_revision.28.Feb.2018.xlsm
    • Unfortunately, Microsoft disables Excel workbooks with macros downloaded from the internet, so the sample size calculator above likely won't run since it contains macros that enable the iterations needed to find sample sizes.
