Abstract |
The paper discusses the predictive ability and the items selected by the Gluecks research organization for their predictive devices are those arrived at by strict analytic multivariate techniques and represent findings that cannot be faulted by criticisms of the Glueck methodology. In 1950, Professor Sheldon Glueck and Dr. Eleanor T. Glueck published "Unraveling Juvenile Delinquency," a multidisciplinary, detailed comparison of 500 delinquent and 500 nondelinquent boys. In 1960, Professor Glueck, at the request of the editors of the "Journal of Criminal Law, Criminology and Police Science," prepared a paper for the issue to commemorate fifty years of publication of that Journal. The first of the criticisms is grounded in the fact that not all individualist used in Unraveling had complete observations on all. 400 items involved in the origin research. The reasons for these missing observations are varied. The nature of missing observations generally decides their impact on an experiment. There are three distinguishable types of missing observations: random, non-random, and indeterminate. |
