Effect Size Matters

“Your book rocked my little statistical world.”

Is your study worth doing? Do your results make sense?

In this jargon-free introduction to effect sizes, you will learn how to answer the toughest questions you will ever hear in a research seminar: “So what? What does this study mean for the world?”

If you want to know;

  • five compelling reasons to report effect sizes
  • which journal editors are insisting authors report effect sizes and why
  • how to calculate effect sizes in a variety of metrics
  • the difference between statistical- and substantive significance
  • how to interpret your results in a way that makes sense to nonspecialists
  • why small effects can sometimes have big consequences

then this is the book for you!
