FAQs About Effect Size.
نویسنده
چکیده
Effect size is the magnitude of the difference between two intervention groups.

Calculated effect size indices are useful when the measurements have no intrinsic meaning, such as numbers on a Likert scale; studies have used different measurement scales; or effect size is examined in the context of variability in subject responses.
