1. A new designer drug, kratom, is becoming popular with the youth in your area. Local police are concerned that this will lead to increased erratic behavior among teens in town. You have been hired to conduct a study to determine the potential effect of this drug on your area.

Identify the following and explain your choices:

• How you will operationally define “erratic behavior.”

• One basic research question you might investigate and one applied research question you might investigate.

• The dependent variable you will use in your study.

• The independent variable you will use in your study.

2. From the research design you have developed for question #1, consider the following: Wilmington University is interested in partnering with you to investigate this phenomenon and would like use WU students to conduct your study.

• What would you have to do first to gain approval to conduct your study?

• Explain why you would have to describe why your study’s benefits would outweigh any potential harm to participants

• Explain why you will need to obtain informed consent from your participants

How do you plan on going about gaining informed consent for your study?

• Explain how you will go about establishing and maintaining the confidentiality of your participants and why you must do so

3. For your study identify one potential threat to internal validity and explain why this would be a potential issue for your design

Next, identify one potential threat to your external validity and again, explain why this would be a potential issue for your design

Could you study be completed using a classic experimental design? Explain why or why not.

4. What type of sampling will you use in your study? Why do you feel this study will be best for your design?

Now, select a different sampling method that you did not select for your study and explain why this type of sampling would not be appropriate based on your study’s design

5. Congratulations- your study was a huge success and Wilmington University would like you to conduct a follow-up study. For this follow-up study you have decided to conduct an email survey, where former participants are asked to fill out a new set of questions.

Name and explain one major problem with using a self-report survey

Next, name and explain one, strength of using a self-report survey for this study

For this type of survey do you feel false reports, interviewing effects or sampling bias would be the biggest threat to validity? Explain your decision by explaining why (or why not) each of the terms would be a potential issue for your study
