The last take to proportions, ergo, are round around a maximum of 2880 students.
Concerning the new testing approach, we working a multistage people sampling method of pick people old 11–fourteen ages into the step 3 head regions of Vietnam (North, Center, and you may Southern area).

Or no scholar don’t fulfill all in the past discussed introduction criteria, we could possibly find several other beginner of the identical sex in the picked category.
