   Abstract:
   Researchers often describe the quantitative effects of interventions using terms related to their magnitude (e.g., large or small) and practical impact (e.g., promising or significant). This article suggests that such descriptors must be used with great caution and much additional context. The article also illustrates some translations of effect sizes that should be meaningful to audiences with limited statistical expertise and, hopefully, make it unnecessary for researchers to apply qualitative descriptors to them.
