Hello, Dr. MEL. Our organization has been asked to assess the effect of public education against drugs on ND. In the MEL courses, I learned about some evaluation techniques, but I can’t recall the specifics to apply them to a real project. Could you please tell me, for instance, what factors to take into account when deciding on the sample size?
