Using the research question : "The general topic is gangs in schools and the research question is "What is the impact of a gang presence on youth in school" The variables that would need to be measured in order to answer the question would be the type of school, demographic characteristics, differences starter gangs and gang formations and strategies for delinquency/intervention protections." Variables & Measurements: How does what you intend to measure represent the concept you are measuring? Discuss the reliability and validity of these measures. Sampling : What is your unit of analysis? What sampling method will you use to gather elements? What are the strengths and weaknesses of this sampling method? Will the results of your study be generalizable? What limitations are there on generalizability based on your sample? Research Design : What research design will you use to answer your research question? Include a diagram of that design if you can. What threats to internal validity does your design rule out and why? What threats to internal validity remain and why? If you were to find a correlation between your independent and dependent variables, what rival hypotheses would you need to rule out before you would consider making a causal claim? Ethical : How will you collect your data? What ethical considerations, such as informed consent and confidentiality, do you need to address in your data collection? How would you do so? Are there any other ethical issues with your research
