In evaluating a program, conducting both interviews and surveys is an example of what method?

The choice of a mixed-methods approach is fitting in this context because it involves combining qualitative and quantitative research methods to gather and analyze data. By utilizing both interviews, which typically provide in-depth qualitative insights, and surveys, which often yield quantitative data, the evaluator can develop a more nuanced understanding of the program's effectiveness and impact.

Employing a mixed-methods approach allows for triangulation of data, where the strengths of one method can help to address the limitations of the other. For instance, qualitative interviews can uncover deeper attitudes or motivations that surveys might not fully capture, while surveys can provide broader generalizations that enhance the understanding of trends observed in the qualitative data.

In contrast, comprehensive evaluation would imply a more holistic view of assessment without the emphasis on methodological diversity. Sequential evaluation refers to conducting methods in a specific order, while single-method evaluation restricts the investigation to just one approach, limiting the depth and breadth of the findings. Thus, the mixed-methods approach stands out as the most effective method for evaluating a program comprehensively.
