  • Briefly restate the purpose of your team’s program evaluation RFP.
  • Describe a situation for which a single-group design might be considered for an evaluation of the general program situation of your RFP (e.g., school anti-bullying program). Why might it be appropriate in this situation? Explain.
  • Given your example, explain the strengths and limitations of a single-group design for use in this evaluation.
  • Would you choose a posttest only or pretest-posttest design? Why?
