Document Summary
We do not prove stuff, we give it supporting evidence. Statistics never tell you 100% you"re right, it"s usually about 95% We just make it seem very likely that a theory is correct. Observation + theory --> hypothesis + predictions --> test --> if test confirms, adds to theory and observations --> observation + theory. Observation + theory --> hypothesis + predictions --> test --> if test fails to confirm, must modify hypothesis. Experimental control: controlled everything so can make causal statement at the end. Lose generalizability (whether what you found in the experiment would exist in the real world) Lab and some field experiments has a lot of control. Correlational studies and field (observational studies) not a lot of control, but doing stuff in the real world. How is cloud cover related to precipitation? (so a relationship) Some uncontrolled variables may make something look like they"re not correlated.
