Most evaluations will use qualitative or quantitative data; therefore, it is possible to use either qualitative or quantitative approaches with all evaluation designs. A qualitative approach is critical in evaluation design because it is used to explore specific aspects of programs and explain the experience of the participants. Besides, the approach provides detailed information that will enhance the quality of the program (Glenwick, 2016). A combination of the two methods improves the evaluation process because the strength of one method balances the limitation exhibited by the other method. The disadvantage of qualitative approach in evaluation design is that the quality of the research presented depends on the researcher’s skills. Moreover, it is impacted by the researcher’s personal biases. Second, the presentation of multiple perspectives makes it difficult for evaluators to reach consensus; thus, they cannot provide a neat executive summary.

A quantitative approach is useful in evaluation design because it provides standardized measures and data collection procedures during the evaluation process to ensure comparability. The limitation of this type of approach is that it provides little contextual data for interpreting results or explaining variations across groups (Glenwick, 2016). Second, it is hard to get a lot of information through structured data collection techniques particularly on topics or programs that are sensitive.
