Document Summary
Spoken in a loose tone (cid:523)i. e. face book"s good or bad(cid:524) Epistemology: study of how we come to know what we know. No evidence to prove negative effects to be true. Who"s considered an authority figure? (cid:523)i. e. nbc or twitter(cid:524) (cid:498)a priori(cid:499) Ex: (ow"s face book"s relation to well-being; negative. Explanation: why is there"s a relation between two variables. Note: not all experiments end at this step. Ex: more tv viewing = less accurate prediction of real life crime (mean world. Ex: cultivation theory: heavy tv-viewing = skewed perspective of reality. Theory: statement of how concepts are related. Hypothesis: specific prediction that"s testable with observation. Operational: (ow a concept"s measured to test hypothesis syndrome) Ex: tv watching = hours per day. Ex: crime accuracy prediction = difference in guessing % of victims vs. actual victim % Deductive (quantitative): start with theory -> end with evidence. Inductive (qualitative): opposite of deductive; start with evidence -> build theory.
