The best way to avoid selection bias is to use randomization. Randomizing the selection of participants into treatment and control groups ensures that the two groups are comparable in terms of observable and unobservable characteristics. Non-randomized evaluations attempt to avoid selection bias by making the control group as comparable as possible, typically by matching on observables. The more information is available for matching, the more convincing this is.

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?

I have designed a large-scale survey about the life satisfaction of low-income families in Hong Kong. Is it appropriate to use the electronic survey through mobile phones?
