Assessing an intervention’s effects on multiple outcomes increases the risk of false positives. Procedures that make adjustments to address this risk can reduce power, or the probability of detecting effects that do exist. MDRC’s Reflections on Methodology discusses how to estimate power when making adjustments as well as alternative definitions of power.
To improve outcomes among high-interest borrowers, policymakers need to understand what is driving usage. This second post in MDRC’s Reflections on Methodology series discusses how a data discovery process revealed clusters of borrowers who differed greatly in the kinds of loans and lenders they used and in their loan outcomes.
Machine learning algorithms, when combined with the contextual knowledge of researchers and practitioners, offer service providers nuanced estimates of risk and opportunities to refine their efforts. The first post of a new series, Reflections on Methodology, discusses how MDRC helps organizations make the most of predictive modeling tools.
Testimony Before the New York City Council Committee on Higher Education
In the City University of New York’s innovative program, CUNY’s least prepared students delay matriculation, beginning instead with noncredit, time-intensive instruction aimed at eliminating developmental needs after one semester, preparing participants for college courses, and improving academic outcomes. An independent evaluation will help determine CUNY Start’s effect on academic success.
In a speech given at a conference sponsored by the French government on the role of experimental studies in reducing poverty, MDRC President Gordon Berlin described how the results of random assignment studies have acted as powerful levers for changing social policy in the United States.
No universal guideline exists for judging the practical importance of a standardized effect size, a measure of the magnitude of an intervention’s effects. This working paper argues that effect sizes should be interpreted using empirical benchmarks — and presents three types in the context of education research.
In these remarks, delivered at Speaker Nancy Pelosi’s National Summit on America’s Children on May 22, MDRC President Gordon Berlin summarizes rigorous research evidence showing that supplementing the earnings of parents helps raise families out of poverty and improves the school performance of young children.
In his testimony before the House Ways and Means Subcommittee on Income Security and Family Support, MDRC President Gordon Berlin argues that the most direct way to alleviate poverty is to tackle the legacy of falling wages, particularly for men with less education.
