0190 F A researcher is interested in whether violent offenders can be taught moral reasoning skills and hopes that these skills might eventually lead to a lesser likelihood for recidivism. He randomly selected a sample of 20 violent offenders. He assigned half to the treatment (moral reasoning skills training) (Mean = 8, SD = 1.41), and the other half to no training (Mean = 4.83, SD = 1.71). Does moral reasoning training increase moral reasoning ability in violent offenders?
