This study is an experiment to determine the effectiveness of high-speed drill on speed and accuracy achievement in the first semester of beginning typewriting at the high school level.

The problem of this study was to determine if juvenile delinquents who commit auto theft without an accomplice differ significantly in certain characteristics from those who commit such thefts with one of more confederates. The characteristics investigated were: (1) scores made on individual scales of the Minnesota Multiphasic Personality Inventory and (2) intellectual ability as measured by the California Short-Form Test of Mental Maturity. Furthermore, the same characteristics were examined to determine if a significant difference existed between each of the groups of juvenile delinquents and a group of juveniles who did not have a record of delinquency and attended Sunday School classes regularly.
