The roundtable concluded with a discussion that focused on three themes: research design and methodology; patterns of effect size; and reporting findings in a meaningful way. First, the research design and methodology should be clearly outlined in the beginning stages of a study. This effort includes identifying the outcomes and any mediators. It may be helpful to use measures that have a reported population standard deviation which provide a framework for comparisons. There may be limitations, however, of using a population standard deviation in a demonstration project or large scale study. In any event, the sample standard deviation should be reported. Research projects inevitably collect large amounts of data in an attempt to answer questions from multiple stakeholders. It was suggested that data collection could be scaled back by outlining an executive summary of findings and drafting results tables before data collection begins. In addition, there was a push for data from large scale national studies be made available for secondary analysis.
