This evaluation relied on "critical multiplism" for the strength of its design.
According to Cook (1985), an evaluation requires multiple realizations in
research questions, data sources, methods, samples, measures, and analyses
to establish the validity of the study. Key findings should reflect points of
convergence among various data sources (triangulation), help attribute
results to program activities, and reduce alternative explanations. in the
spirit of critical multiplism, we incorporated both qualitative and quantitative
components in the evaluation of Community Gardens.
