Wading Through the Data Swamp:
Program Evaluation 201

How Can Jack Use This Statistical Information To Better Promote His Program?

Jack now knows that, as a result of his program, fewer of his kids drink alcohol, compared to the kids who were not in the program at posttest. Yeah! Jack can relay this information to teachers, principals, parents, and others in the community. This information gives Jack's program more credibility and could increase registration for his program next year.

Jack can also use the information about marijuana use within his participant group to promote his program. Jack may search for funding to address the marijuana issue. By completing an evaluation of his program and finding out that there is a marijuana problem, Jack has established a need for funding.
