I have read some discussions about using the pre-experimental study for the elderly sleep intervention. May I ask the reason that it is called pre-experimental instead of calling it experimental design?

Thanks for asking. The distinction lies in whether there is a control group in the study design. In previous posts, there is only one treatment group for a novel intervention; that’s why it is called pre-experimental design.

I intend to conduct a random sampling method survey on the service utilization of sheltered workshops for people with disabilities in Hong Kong. Is clustered random sampling the best approach?

Hi, I realized that it seems the concept “outcome” is different from the term “output”. Taking the grandparent training project as an example, what is the “outcome’ referable?
