Assignment Steps
Resources: Microsoft Excel®, Signature Assignment Databases, Signature Assignment Options, Part 3: Inferential Statistics
Scenario: Upon successful completion of the MBA program, say you work in the analytics department for a consulting company. Your assignment is to analyze one of the following databases:
 Manufacturing
 Hospital
 Consumer Food
 Financial
Select one of the databases based on the information in the Signature Assignment Options.
Provide a 1,600word detailed, statistical report including the following:
 Explain the context of the case
 Provide a research foundation for the topic
 Present graphs
 Explain outliers
 Prepare calculations
 Conduct hypotheses tests
 Discuss inferences you have made from the results
This assignment is broken down into four parts:
 Part 1 – Preliminary Analysis
 Part 2 – Examination of Descriptive Statistics
 Part 3 – Examination of Inferential Statistics
 Part 4 – Conclusion/Recommendations
Part 1 – Preliminary Analysis (34 paragraphs)
Generally, as a statistics consultant, you will be given a problem and data. At times, you may have to gather additional data. For this assignment, assume all the data is already gathered for you.
State the objective:
 What are the questions you are trying to address?
Describe the population in the study clearly and in sufficient detail:
 What is the sample?
Discuss the types of data and variables:
 Are the data quantitative or qualitative?
 What are levels of measurement for the data?
Part 2 – Descriptive Statistics (34 paragraphs)
Examine the given data.
Present the descriptive statistics (mean, median, mode, range, standard deviation, variance, CV, and fivenumber summary).
Identify any outliers in the data.
Present any graphs or charts you think are appropriate for the data.
Note: Ideally, we want to assess the conditions of normality too. However, for the purpose of this exercise, assume data is drawn from normal populations.
Part 3 – Inferential Statistics (23 paragraphs)
Use the Part 3: Inferential Statistics document.
 Create (formulate) hypotheses
 Run formal hypothesis tests
 Make decisions. Your decisions should be stated in nontechnical terms.
Hint: A final conclusion saying “reject the null hypothesis” by itself without explanation is basically worthless to those who hired you. Similarly, stating the conclusion is false or rejected is not sufficient.
Part 4 – Conclusion and Recommendations (12 paragraphs)
Include the following:
 What are your conclusions?
 What do you infer from the statistical analysis?
 State the interpretations in nontechnical terms. What information might lead to a different conclusion?
 Are there any variables missing?
 What additional information would be valuable to help draw a more certain conclusion?
Format your assignment consistent with APA format.
