CRJ 716 Practice Questions for the May 2 Review session Law Enforcement: What are the factors that influence salaries in law enforcement? This series of problems uses police starting salary (minimum salary) as the dependent variable and asks questions that require different inferential procedures to examine a series of possible independent variables. Use the questions in each section to help you determine the correct inferential procedure. The dataset is LEMAS – an annual collection of data from US criminal Justice agencies. This file is data from 2013. Q1. Do police agencies that reimburse college education costs pay higher average salaries?

What is the level of measurement of the dependent variable? 3. What is the N of your sample? 4. What is the NULL Hypothesis? ` 5. What is the RESEARCH hypothesis? 6. What would the appropriate inferential test be? Q2. Does the REGION of the US have an impact on the minimum salary paid to law enforcement officers? Variables: REGION2 – Region of the USA and PAY_SAL_OFCR_MIN – Minimum salary 1. What is the level of measurement of the dependent variable? 2. What is the level of measurement of the independent variable? 3. State the Null Hypothesis in words. 4. State a non-directional Alternative / Research Hypothesis in words. 5.

Variables: POP2012 – census population in 2012, BDGT_TTL – agency budget and PAY_SAL_OFCR_MIN – Minimum salary 1. What is the level of measurement for each variable? POP2012: BDGT_TTL: PAY_SAL_OFCR_MIN: 2. What inferential procedure can be used to explore this question?
