Brief summary: 

The Kansas City preventive patrol experiment: Police Foundation. Retrieved from

https://www.policefoundation.org/projects/the-kansas-city-preventive-patrol-experiment/

The experiment focused on the following research questions:

· Would citizens notice changes in the level of police patrol?

· Would different levels of visible police patrol affect recorded crime or the outcome of victim surveys?

· Would citizen fear of crime and attendant behavior change as a result of differing patrol levels?

· Would their degree of satisfaction with police change?

Pick ONE of the research questions above and complete the following five exercises. Use the attached worksheet to answer the questions. You will need to put your answers on this word document as well

The experiment focused on the following research questions:

· Would citizens notice changes in the level of police patrol?

· Would different levels of visible police patrol affect recorded crime or the outcome of victim surveys?

· Would citizen fear of crime and attendant behavior change as a result of differing patrol levels?

· Would their degree of satisfaction with police change?

Pick ONE of the research questions above and complete the following five exercises.

1. Identify one independent variable from the selected research question.

2. Indicate how the independent variable identified in #1 could be measured (conceptualize, operationalize, and describe the level of measurement for this variable).

3. Identify one dependent variable from the selected research question.

4. Indicate how the dependent variable identified in #3 could be measured (conceptualize, operationalize, and describe the level of measurement for this variable).

5. Express the research question in a measureable hypothesis statement (ensure that the hypothesis statement includes the independent variable and the dependent variable you identified in items 1 and 2 above). Use the following structure to help formulate your answer:

____ with ____ are more/less likely to ____ than ___ without ______

(subjects) with (independent variable) are more/less likely to (dependent variable) than (subjects) without (independent variable)

Help with the Unit 3 Assignment

Identifying variables and creating a testable hypothesis.

1. Take is slow. Wait for the live seminar discussion so that you are better informed of what is being asked (we will cover variables and hypotheses in the unit 3 live seminar).

2. Review variables from unit 2.

3. This is a work sheet. I do not want long answers for each of the 5 questions. I do not want students repeating themselves as they move from question to question.

4. Pick ONE research question from the Kansas City Preventive Patrol Experiment

5. Determine 1 Independent variable (IV)

6. Discuss how you would measure this IV (think in terms of one simple way).

7. Determine 1 dependent variable (DV)

8. Discuss how you would measure this DV (think in terms of one simple way).

Do not focus on these words: Conceptualization and operationalization

9. Take the 2 variables and put them in a testable hypothesis. Use my exact hypothesis example statement. I just want you to fill in the blanks. Do not write the statement from scratch.

_______ with _______ are more/less likely to ________ than _____ without _______

There are 5 blanks.

Use 1 or 2 words for your subjects. These words will go in blank # 1 and blank # 4

Use your IV (1- 3 words) and put it in blank # 2 and blank #5

Use your DV (1- 3 words) and put it in blank #3

Pick a relationship. Use the word “more” or “less.” Use one of these words only.

APA is not needed for this assignment.
