The internet is host to a wealth of information and much of that information comes from raw data that have been collected or observed.
Many websites summarize such data using graphical methods discussed in this chapter.
Find a website related to your major that summarizes data and uses graphs, and share it with the class. Let us know how it relates to your major and why it is of interest to you.
Scenario: You are submitting an application to a professional conference on data-driven decision making. The application has two parts:
Providing information to the conference organizers.
Creating a presentation for the conference audience.
Steps to complete: In Week 9, complete and submit your assignment in Blackboard using the following steps:
STEP 1: Visit one of the following newspapers’ websites: USA Today, New York Times, Wall Street Journal, or Washington Post. Select an article that uses statistical data related to a current event, your major, your current field, or your future career goal. The chosen article must have been published after the start of this term.
Examples may include:
Award shows (Oscars/Emmys/Grammys)
Human rights issues
The article should use one or more of the following categories of descriptive statistics:
Measures of Frequency – Counting Rules, Percent, Frequency, Frequency Distributions
Measures of Central Tendency – Mean, Median, Mode
Measures of Dispersion or Variation – Range, Variance, Standard Deviation
Measures of Position – Percentile, Quartiles
Note: Once you navigate to a publication’s website, it may be easiest to do a search with a statistics-related word (ex: standard deviation).
The publications listed are suggestions. If you find an article from another source OR if you are uncertain the article contains all of the information necessary to complete the assignment, please let your instructor know. Your instructor can help you determine whether it is a good fit for this assignment. If you need additional help locating an article, contact a Strayer librarian for more assistance. Remember to review the examples in the Week 6 Discussion.
STEP 2: Using the data from your article, use the template included in this assignment to answer the following questions asked by the conference organizers. Remember to consider their expertise as mathematical professionals and use appropriate language to communicate your findings:
Highlight the purpose of the article and the problem it is trying to solve. Think summary, in bullet-form.
Explain how the article uses descriptive statistics to communicate information found in the study and/or any conclusions/solutions.
Explain how the article applies to the real world, your major, your current job, or your future career goal.
Recommend solutions using the mathematical and visual data provided.
STEP 3: An additional part of the application process requires you to create a presentation based on the information provided in the template.
Based on your topic, choose an audience (outside of the field of mathematics) that could benefit from the information you will present. For example, this could be your local city council member, staff or administrators of a school, or employees at a company.
Analyze the data in the article to determine the best visual (graph or chart) to tell the story to your audience.
In PowerPoint or other presentation tool, create one visualization of the data appropriate for the conference audience. NOTE: If the article already contains a visual, you must create a different type of graph or chart.
Identify the audience and explain how the audience can benefit from the data.
Recommend your identified solutions using language appropriate for the audience.
STEP 4: In the notes section of your final slide, answer the following questions:
Explain why you chose the audience in Part B.
Describe how the visuals used in the PowerPoint are appropriate for the audience.
STEP 5: Format your presentation according to the Strayer Writing Standards. For assistance and information, please refer to the Strayer Writing Standards link in the left-hand menu of your course. Check with your professor for any additional instructions.
STEP 6: Submit your assignment in two parts:

Problem OneGary Seitz is director of procurement for the Forest Medical Center in Oak Park, Illinois. His medical center recently purchased more than 300 new side tables for the patient rooms from Quick-and-Cheap Furniture. His team, however, is not happy with the paint quality of these tables. They feel the firm providing the tables was rushed to get the order out and did not do a great job.
They have examined each of the 312 tables that they have received so far and found the following defects, listed in alphabetical order:

Draw two conclusions about the quality of the patient tables that Quick Furniture has shipped to the Forest Medical Center.Submit both your Word and Excel files.
Problem TwoTed Short, manager of procurement at the Lake Luna Medical Center (LLMC), is starting a process to examine at the general process that is followed at his center for procurement of medical supplies at his facility. His first step is to develop a flowchart for the current process that employees at his center follow. He has asked you to draw that flowchart for him and make any obvious changes to shorten the process.
Here are the key steps that are followed:
The LLMC employee fills out a paper requisition and sends that to his department head for approval.The department secretary first examines the requisition to see if all needed information is present. If it is, then she sends to the department head for approval. If not, she returns to the employee for any needed corrections. The employee then returns the requisition to the department secretary for review again.Requisitions with the correct information are sent to the department head.The department head reviews the item to determine if the material requested seems appropriate. He may contact his employee to discuss any questions he might have. If he feels it is inappropriate, then he rejects the request and sends it back to the employee. If he feels it is appropriate, then he checks the budget to see if there are sufficient monies in the budget to pay for this. If there are not, then he rejects the request and sends it back to the employee. If there are sufficient funds, then he approves them.If the requisition is approved, then the department secretary sends the requisition to a member of the LLMC Procurement Team. The LLMC procurement specialist checks to see if the suggested vendor on the requisition is on the approved vendor list (AVL).If not, he sends the request back to the department secretary and the process starts all over if the LLMC employee wants to continue to pursue it. If the employee does not, then the requisition is terminated.If the vendor is on the AVL, the LLMC procurement specialist checks to see if a quote is required, either based on the type of equipment and material required or on the amount of the purchase. If no quote is required, the procurement specialist transmits the PO to the vendor for execution.If a quote is required, then the specialist contacts the vendor and asks for a quote. If the quote is satisfactory based on past purchases of such items, the specialist approves the quote and places the order. If the quote is too high, the specialist contacts the LLMC employee and asks for another vendor to check. The procurement specialist then checks the second vendor. Usually, a procurement specialist will have to check only two vendors at most.If the specialist cannot find a vendor with it suitable price after two tries, then the PO is cancelled.When the specialist finds a vendor who submits a suitable quote, the transmits the PO to the vendor for execution by US postal service or by telephone.The procurement specialist then logs the transaction into the financial system.The procurement specialist then forwards the request to the Accounts Payable Department for payment when the receipt of the materials and equipment ordered, if acknowledged.InstructionsUse Microsoft Word to complete the following:
Develop a flowchart for this process.Suggest three improvements, based on total quality management, that Ted Short can use to make the current process more efficient.Submit your Word document(s).
