Research Design Group work Group: Non-experimental Article 1 Title: Early Intervention and Juvenile Delinquency Prevention: Evidence from the Chicago Longitudinal Study Type of design: Longitudinal Longitudinal studies employ continuous or repeated measures to follow particular individuals over prolonged periods of time—often years or decades. They are generally observational in nature, with quantitative and/or qualitative data being collected on any combination of exposures and outcomes, without any external influenced being applied. [ CITATION Car15 \l 1033 ] Research design and results: This study investigated the role of an early educational intervention and child-, family-, peer-, and school-level predictors on court-reported juvenile delinquency. Data were provided from the Chicago Longitudinal Study, an ongoing investigation of the scholastic and social development of more than 1,500 low-income youths. Preschool intervention was associated with reductions in the incidence, frequency, and severity of juvenile delinquency by age 18. This means that the results were the expected ones, the research design was congruent with the hypothesis that the educational intervention would lower the incidence of juvenile delinquency, this is a longitudinal non-experimental study because it traces the effects of an already ongoing campaign and the authors didn’t have any effect over the variables that were observed. Article 2 Title: The Association Between Current Intergenerational Family Relationships and Sibling Structure Type of design: Correlational Correlational research is a type of nonexperimental research in which the researcher measures two variables and assesses the statistical relationship (i.e., the correlation) between them with little or no effort to control extraneous variables. [ CITATION Chi15 \l 1033 ]

relationship between high levels of delinquency and victimization was stronger for violence-related delinquency than for property-related delinquency. The general usage of surveys is clearly varied, people could use surveys in any of the other research methods including in the experimental ones. The use of surveys is very clear, the authors wanted or needed to analyze a grand quantity of information in a clear and organized way, the results are optimal since they make it easier to correlate risk factors and differentiate between genders in a very palpable way. The survey helps direct the research towards the variables we want to observe. The problem with surveys is the reliability of the information since it is obtained though self-reported information. In this case I think due to the size of the sample it is justifiable.
