Document Summary
Hypothetico-deductive method: test philosophical ideas through observation. Five steps: examine past knowledge/research, form a theory, operationalize the theory into a hypothesis, test hypothesis. Usually en masse trying to generalize to all people: rationalize theory. The variable that you want to be able to predict. The variable that you think will predict your dv. The iv must be experimentally manipulated in order to imply causation. 2 dvs: we consider both variables in a correlational analysis to be outcomes to re ect the lack of causal conclusions that can be drawn. Random sampling: need to generalize any data. Sept. 16, 2013: icecream sales correlated with drowning deaths there is no causality. More icecream is sold during summer when more people are swimming. Covariance and prediction: one predicts the other when they occur together. If you have a causal hypothesis, correlations will always support the hypothesis. A de ned iv (predictor) and dv (outcome)
