6. Research Design Null Hypothesis The D.A.R.E. Program (A) does not affect the subject(s) drug use (B). There are other factors that will influence drug use Research Hypothesis When D.A.R.E. participation (A) increases, drug use (B) will decrease. D.A.R.E. participation may have a temporary influence on the subject(s) drug use.
7. Experimental, Pre/Post test Randomized 2 group design O 1 X 1 O 2 R O 1 O 2 R = Random Assignment (schools with DARE as well as schools without it) O = Observation (surveying DARE participants and Non-DARE participants, regarding their drug use history) X = Treatment (DARE program)

9. Alternative hypothesis Other factors for the correlation between A and B Spurious Causation A C B C = Prior drug convictions C = Prior drug convictions C = Lack of participation C = Lack of participation A = Drug Use B = Unsuccessful DARE program A = Drug Use B = Unsuccessful DARE program C = Family C = Family A = Drug Use B = Unsuccessful DARE program
