Descriptive Statistics Assessment Description

Project instructions:
As you complete the assessment work in this unit, you may find it helpful to consider the questions below. You are encouraged to discuss them with a fellow learner, a work associate, an interested friend, or a member of the business community, in order to deepen your understanding of the topics.

The term, inference, refers to parameter estimation and hypotheses testing. Hypothesis testing could be conducted based on the p-value (critical value), or based on construction of confidence intervals.

Are you confident in making inferences for business decisions based on confidence interval and p-value (or critical value) approaches?
How would you use the confidence interval approach to make inferences for business decisions, based on the difference between two population rates?
Do you have a preference between the two approaches for making statistical decisions to support business strategy? If so, why?

Assessment Instructions
To complete this assessment, use the Campus Crime Data Excel file, linked in the Assessment Resources. This file contains two data sheets:

The Campus Crime Data for Minnesota (2009?2011) page provides actual data generated by the U.S. Department of Education’s Campus Safety and Security Data Analysis Cutting Tool.
The Campus Crime Data Codebook explains the labels used in the Campus Crime Data sheet.
Practical Application Scenario
As a result of recent campus safety concerns at Capella University, you have been engaged by campus security team leaders to gather and analyze data about on-campus crime rates in schools in the state of Minnesota. Crime data from 181 Minnesota campuses has been compiled in the Campus Crime Data file. Write a management report for campus security team leaders analyzing and evaluating campus crime data for Minnesota. Include your findings and recommendations for your clients. In your report, be sure to examine the following:

What crimes were most commonly committed on Minnesota campuses between 2009 and 2011? Based on the data, would you say the crime rates decreased or increased from 2009 to 2011?
The campus security leaders believe that the total crime rate in public institutions is more than that in private institutions. They have asked you to test that hypothesis. Describe your results.
Your clients would also like you to develop a 95 percent confidence interval for the difference in total campus crime rates between public and private institutions in Minnesota. Report your results.
What, if any, ethical issues should concern you in conducting your research?
Complete your report in a Word document, pasting in whatever relevant tables and graphics you need to support your findings. Place your tables and graphics within the text and be sure to clearly title them. Your tables and graphics must be legible and suitable for inclusion in a management report.
