Answer:
Cost Benefit Analysis
Step-by-step explanation:
Cost benefit analysis research is "a systematic process for calculating and comparing benefits and costs of a project. A cost benefit analysis finds, quantifies, and adds all the positive factors (the benefits). Then it identifies, quantifies, and subtracts all the negatives (the costs). The difference between the two indicates whether the planned action is advisable."
If Karen is doing a cost benefit analysis well she must be sure she includes all the costs and all the benefits and properly quantify them in the community service program.
