What is an evaluation?

Evaluation is a process that critically examines a program. It involves collecting and analyzing information about a program’s activities, characteristics, and outcomes. Its purpose is to make judgments about a program, to improve its effectiveness, and/or to inform programming decisions (Patton, 1987).

Do you test a theory or hypothesis?

But, because theory is a result of scientifically rigorous research, it is more likely that the theory is true (as compared to a single hypothesis). Any theory can (and should) be tested but the tests must be scientifically conducted and reviewed by many, qualified researchers/scientists.

What makes a good theory?

A good theory in the theoretical sense is (1) consistent with empirical observations; is (2) precise, (3) parsimonious, (4) explanatorily broad, and (5) falsifiable; and (6) promotes scientific progress (among others; Table 1.1).

defined as a proposed explanation (and for typically a puzzling observation). A hypothesis is not a prediction. Rather, a prediction is derived from a hypothesis. A causal hypothesis and a law are two different types of scientific knowledge, and a causal hypothesis cannot become a law.
