A headline says, 'New note-taking method has a huge effect.' The article reports an effect size of d = 0.20 on a quiz score. Which interpretation is best?
A
Any positive effect size proves a huge improvement.
B
The result suggests a small average difference, so the headline's 'huge effect' wording is exaggerated.
C
The method had no effect on any student because 0.20 is below 1.00.
D
An effect size of 0.20 means scores improved by 20 percentage points.
