Document Summary
Pos 3122 (january 10) (extra credit will mainly be on harry potter questions) The comparative method: science consists of developing general theories about how the world works, step 2: derive hypothesis from those theories. Theories explain why: step 3: make observations to test hypothesis (collect data). Hypothesis is one sentence statement on what you expect to happen: step 4: analyze the data. Correlation: happens together a lot, when x moves y moves. Temporal precedence: something doesn"t happen before hand. For example, the fire truck doesn"t come before the fire. Non-spuriousness: more involved parents send their kids to private school who are more likely to do better in the sat (triangle is a spurious diagram) z affects the x and y relationship. Theory: maps out the causal process by which x influences y. Sat depends on whether you went to private school or not. What is affecting what x y: x happens first, then y, theory is a long explanation.
