Replication the residents: data is usually presented by showing just individuals, rather than averaging across all people, difficult to do statistics, but procedures are developing. Allows researchers to establish cause-and-effect relationship with one subject. Flexibility: the researcher is free to modify the treatment or change to a new treatment if a subject fails to respond to treatment. No need to standardize treatment across groups: a single subject is used. Relationship among variables is for only one subject: may threaten external validity (generalization) Reliance on graphs to demonstrate that treatment effects are real: treatment effects must be large and immediate to produce a convincing graph. Evaluation is the systematic assessment of the design, implementation or results of an initiative for the purposes of learning or decision-making.
