Document Summary
Empiricism: verification via observation: proposals are subjected to a test, perform an experiment and obtain data. Science: a process of gathering knowledge about the world, asking questions about the world, making a hypothesis about nature of things and testing this hypothesis, provides a systematic approach. All good science should have a clear articulate, hypothesis based on theory based predictions. Tool for determining nature of relationship between variables. Manipulate and observe the effects of a variable on another variable: manipulate type of stimulus (visual or auditory, observe effects of stimulus on reaction time. Dependent variable: variable that is measured: change in dependent variable is assumed to be a result of change in independent variable. Independent variable: (have 2 levels or more) manipulated variable by experimenter: observe effects of independent variable on dependent variable. Acoustic stimuli have shorter reaction times than visual stimuli. 2 groups in a study means that is one independent variable time of assessment (2 levels)
