The scientific approach is based on a position of skepticism and we generally use empirical methods to observe various phenomenon and you apply that to. Causation: establish temporal precedence, covariation of cause and effect, eliminate alternative explanation. Basic research (pure research) is set up to answer general questions for general knowledge sake. Applied research (implied) is set up to answer practical questions and apply some kind of program evaluation. When generating hypotheses, it is useful to identify the variables first and then determine if increases or decreases of one of those variables has some kind of effect on the other variable. Hypothesis: a statement or a claim about how variables relate to one another. Simple hypothesis: a statement or claim about the relationship of two variables. Complex hypothesis: making a statement or claim about two variables that depend on the influence of another variable.
