Direct linkO'Toole, John Mitchell; King, Robert A. R. – Language Assessment Quarterly, 2010
This quantitative study intends to better understand the impact of the location of the first deleted word upon the estimation of text difficulty yielded by successive cloze tests based on random deletion from a single passage. The variation in sampling of language features across five cloze tests based on the same passage is random and thus not…

In this set of four supplemental tables, the authors compare the baseline test scores of the treatment and matched control group samples observed in each year after KIPP entry (outcome years 1 to 4). As discussed in Chapter III, the authors used an iterative propensity score estimation procedure to calculate each student's probability of entering…

Althauser, Robert P.; Rubin, Donald – Amer J Sociol, 1970
The use of matched sampling in experimental and nonexperimental research ahs been frustrated by the problems of attrition and incomplete matching. The amount of attrition of sample size and incomplete matching are shown to be a function of various aspects of the research, including the level of measurement of the matching variables, the sampling…

Peer reviewedRosenbaum, Paul R. – Journal of Educational Statistics, 1986
Using data from the High School and Beyond, this article presents statistical procedures to estimate the effect of dropping out of high school on cognitive achievement test scores. Each sampled dropout is matched to a student remaining in the same school. Methods for addressing the possible omission of covariates are described. (BS)

Burghardt, John; McConnell, Sheena; Meckstroth, Alicia; Schochet, Peter; Johnson, Terry; Homrighausen, John – 1999
The National Job Corps Study was conducted in 1994-1996 to provide a thorough and rigorous assessment of the impacts of the Job Corps on key participant outcomes. To ensure that the study was well implemented, a study team from Mathematica Policy Research, Inc., (MPR) investigated outcome and admission (OA) procedures in each Job Corps region and…
