Document Summary

Because they"re other variables that may better explain your findings, or the observed relationship. Only on the basis of experimental design can you make causations. You can never make statements in causality, but you can make and draw many reasonable inferences. Ex - the more a person is athletically, the more of an opinion they"re gonna have about steroid use - hypothesis. Public discourse - a complex concept that is carried out in media. The role that variables play in the research process. Hypothesis is essentially a statement of causality - it states a causal relationship among two variables. Dependent variable is the one that is acted upon (cause, consequence, prepare for change) Ex - attitude towards drug use - dependant on the person"s athletic socialization. Independent - it does whatever the hell it wants to. Ex - athletic socialization - these people who are strongly active will have a stronger opinion.
