7  Recalculation methods ✎ Very rough draft

7.1 Recalculating p-values

  • From test statistics: statcheck + its false positives
  • From summary statistics; accounting for rounding

7.2 Recalculating effect sizes

  • Cohen’s d and partial eta-squared
  • Not just for recalculating already reported effect sizes to check consistency, but also calculating ones not reported to check plausibility
  • Standardized + SDs to unstandardized, with plausibility of both

7.3 Confidence intervals and bounds

  • Recalculating confidence intervals for all the above

7.4 Recalculation under partial information

  • Bounds etc., e.g., within-subjects t-test

7.5 Other recalculations

  • Beta and SE
  • SEM degrees of freedom
  • Running regressions from correlation tables
