How do political scientists gather data. quantify data, analyze data statistically, and attempt to validate (or invalidate) hypotheses

Political scientists usually carry out research studies in order to prove or to predict a future occurrence. During the studies, they collect, analyze and manipulate data in order to obtain data result that are support generalization. If the frequency of the generalization obtained is high [that is, if other scientist get similar results], then a theory can be developed from the generalization.
