Effectiveness evaluations do not include

A) Quasi-experimental designs
B) Experimental designs
C) Statistical methods
D) Case study methods

Effectiveness evaluations typically do not include case study methods as they are considered less rigorous and objective compared to quasi-experimental and experimental designs. However, case studies can still provide valuable insights and information in certain situations. Quasi-experimental and experimental designs, along with statistical methods, are commonly used in effectiveness evaluations to establish causality and measure the impact of interventions or programs.
