DEVRY JADM350 WEEK 3 AND 4 DISCUSSION

WEEK 3Sampling Techniques—Hidden Populations (graded)Do you have access to any hidden population that is involved in some sort of deviant or criminal activity? If not, provide a hypothetical hidden population that you would be interested in researching.Sampling Techniques—Techniques (graded)Think about the hidden population you’ve identified. Choose one of the following research methodologies and describe for your peers how you would set up a means to study this group. (Cluster sampling; quantitative; qualitative; mixed methods; stratified sampling; systematic sampling.) Discuss why you believe this methodology would work well in studying your hidden population.WEEK 4Deciding How to Research (graded)You are the Shift Lt. in charge of a DUI task force for your small department. This is a very specialized and expensive component of your department’s efforts to reduce driving under the influence of either drugs or alcohol, and you have been told to research the success of your task force for the past 6 months and to present these findings to the Chief and Deputy Chief at the next Command Briefing scheduled for this coming Friday. Your task force consists of 12 mobile units, each with an officer having specialized training, two K9 units, and the 6-month span from June 1 through 12/31 of this past year. To research this, you will have to resort to sorting through the tickets written during that time frame for details and you can use daily/weekly/monthly staff reports for overall statistics.You must post at least three times each week. Explain your experiment by day 3 (your main posting) of this class week. Then on day 4, you will go to any fellow class student and critique their experiment on the grounds of internal and external validity, while suggesting ways to improve the design and validity of their experiment. Last, your third posting (you are welcome to post more) will be in response to the critique made of your initial posting by the classmate who is immediately before you in the alphabet.Real-World Complications (graded)Given the sample in topic 1, what real-world complications could you see in being able to perform the DUI research listed above, and as that Shift Lieutenant, what systems or procedures would you implement to ensure your follow-up report was more accurately and meaningfully created? To validate your conclusion about real-world complications, you might want to do a quick library search to locate studies done concerning DUI research. What complications did those researchers discuss?
