q2 · i? · associational · r?
The study's summary reports advocates' claims about attendance and states the study's finding: "There was no quantitative evidence that the 4dsw improved student attendance." This is a null finding; equivalence was not tested.
"Advocates of the 4dsw argue that the shorter week saves money, improves student attendance, and helps recruit and retain teachers in rural districts."
