Document Summary
Example: h0 = playing violent video games is not related to aggressive acts. A prediction about what will happen between the variables of interest. Ex: theory = being exposed to violence will foster more violence. Ex: hypothesis = children who play violent video games will act more. Hypothesis = a testable (falsifiable) statement (not a question); no effect aggressively than those who don"t. Null hypothesis (h0) = always states that there is no difference between the groups, or no relation between two variables. Hypothesis/alternative hypothesis) = states a relation between the two; an effect on the two being violent. Research hypotheses can be directional or nondirectional. Non-directional research hypotheses: (some different or relation, but not specific) Be sure to name the two variables (characteristics) Example: h1 = there"s a relation between the playing violent video games and. Group 1 and group 2 will be different; there"ll be some relationship between the variables.
