Document Summary
Experiment - researcher manipulates one/more variables, attempts to control extraneous factors, measures, how manipulate variables affect participants" responses. Dependent variable - response measured to determine whether independent variable has produced effect. Isolate factor of interest, tinker around w/ it, try to keep aspects of situation constant & see what effects tinkering produces. Although experimental method has pitfalls & limitations, well-crafted experiment is scientific work of art - is the best scientific tool available to draw clear conclusions about cause-effect relations. Control - reflects ability to regulate/exercise direction over something. Choose types of dependent variables measured & how & when they will be measured so that effects of independent variables can be assessed. Regulate other aspects of research environment, including manner in which participants exposed to various conditions in experiment. Goal of having control - to enable researchers to conclude that variable they manipulate is cause of any obtained effects on behavior.
