First find out what other people have already discovered about the same or similar ideas. Hypothesis a testable prediction about the conditions under which an event will occur. Statement about the cause and effect relationship between two variables. A quasi-experimental approach samples pre-existing groups and then treats them as if they are different experimental groups. Operational definition a specific procedure or measure that one uses to test a hypothesis. If you have a good operational definition, your measure if valid it measures what it is supposed to measure.
