What is the effect size when general education is done correctly?

• A. 0.50
• B. 0.25
• C. 1.00
• D. 0.73

Answer: (D)

Effect size shows how big the real-world impact of an intervention is, not just whether it works. When general education is implemented correctly, the benefit tends to be substantial, often around a large effect size. A value of about 0.73 means the average outcome for students in well-run general education is roughly three-quarters of a standard deviation better than the comparison group. That level of difference is considered a strong, practical impact, indicating meaningful improvement in performance or outcomes. The other options represent smaller or unrealistically large effects, so 0.73 best reflects the intended, substantial benefit of proper general education.
