Effect size

A standardized measure of how large a study's result actually was (commonly expressed in standard deviations), used to compare findings across studies and to avoid mistaking a modest result for a dramatic one.

Defined in 2 GAGE programs, which carry 3 distinct definitions of it. The wording above is taught in AI Literacy & Professional Conduct.

How each discipline defines it

The same term does different work depending on who is using it. These are the definitions as each program teaches them, unedited.

Engineering Judgment and Professional Formation

A measure of how large a reported difference actually is, as distinct from whether it is statistically detectable at all; used in a synthesis matrix alongside a reported mean to judge whether a headline comparison between two methods reflects a meaningful practical gap or one that is technically present but small enough not to drive a real engineering decision on its own.

AI Literacy & Professional Conduct

A standardized measure of how large a study's result actually was (commonly expressed in standard deviations), used to compare findings across studies and to avoid mistaking a modest result for a dramatic one.

Engineering Judgment and Professional Formation

The actual magnitude of a reported difference or improvement, as opposed to whether that difference cleared a statistical significance threshold. A statistically significant result can still have an effect size too small to matter for an engineering decision, per Section 3K.
