It is a convenient sampling, which lacks representativeness. I am afraid that the funders may challenge your choice of data collection method unless you can prove it is the best way. In a scientific survey, samples should be selected from a well-defined population by a probability sampling method.

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?
