Document Summary
Inject motion into one variable and see what kind of effect that has on the variable. Get this from observation of world around us, see things we don"t understand and get curious, see problems and want to solve them. Eventually you"ll have data that can be answered with measurable. Manipulate the independent variable and see the effect through the dependent variable. Correlation in not causation, but it can invite causation. However we just don"t know what is causing what. Need direct arrow from independent to dependent also be true. The only thing that has been manipulated is the one we want to wiggle. Make observations before and after lecture; use same group. Issues with this kind of experiment with confounding variables. Experimental group and controlled group (2 groups) Former attends the lecture, the latter attends different lecture. Issue with self-selection (i. e. , happier people choose to take this lecture in general as opposed to other.
