Three types of evaluation methods are commonly recognized, which are experimental, quasi-experimental, and observational or case study designs. Experimental designs use random assignment to compare the effect of intervention between otherwise equivalent groups (for example, comparing a randomly assigned group of students who took part in an after-school reading program with those who didn't). Quasi-experimental methods make comparisons between groups that aren't equal (e.g. program participants vs. those on a waiting list) or use of comparisons within a group over time, such as in an interrupted time series in which the intervention may be introduced sequentially across different individuals, groups, or contexts. Observational or case study methods use comparisons within a group to describe and explain what happens (e.g., comparative case studies with multiple communities).

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?
