Discussion Post: The Non Probability Sampling Strategy
A researcher decides that they want to understand how drug dealers gain and defend territories (i.e. street corners, neighborhoods, specific locations). Additionally, the researcher believes that the most successful drug dealers are able to defend their territories without violence. The researcher believes this is tied to the number of years in the business. To learn how long drug dealers have operated, the researcher looks at all of the adult arrest records for known drug dealers in the city.
Question I. What type of sampling method does the researcher use? Is it a probability or non probability sample? Why or why not?
Question II. Based on this information how does the researcher define the following variables:
• Years as a drug dealer
• Violent activities
• Territory
Question III. Based on this information how might the researcher measure the following variables (include their level of measurement):
• Years as a drug dealer
• Violent activities
• Territory
Question IV. Is there any information that the researcher may be missing by looking at just the arrest records? What is missing?
