Signature Assignment

About Your Signature Assignment

This signature assignment is designed to align with specific program student learning outcome(s) in your program. Program Student Learning Outcomes are broad statements that describe what students should know and be able to do upon completion of their degree.

Purpose of Assignment

The purpose of this assignment is for students to synthesize the concepts learned throughout the course, provide students an opportunity to build critical thinking skills, develop businesses and organizations, and solve problems that require data.

Case 1: Analyzing Server Downtimes

Cloud Data Services (CDS), headquartered in Memphis, provides information technology services, specifically, application hosting services in the cloud for several clients in the southern United States. CDS hosts software applications on their network servers. While CDS has achieved great success and customers rate CDS’s services highly, lately, some customers have been complaining about downtime on one of the primary network servers. The given dataset contains the downtime data for the month of November. Your task is to study the downtime data and make a short presentation to the CDS’s management. Use the data analytics skills learned in Week 3 of your QRB/501 course to analyze the downtime data.

Tasks:

1. Using Microsoft Excel’s Pivot Tables, construct a frequency distribution showing the number of times during the month that the server was down for each downtime cause category (This data is found in the Signature Assignment Excel Template.)

2. Develop a bar chart that displays the data from the frequency distribution in part 1.

3. Develop a pie chart that breaks down the percentage of total downtime that is attributed to each downtime cause during the month.

4. Evaluate the mean, median, standard deviation, and variance of the downtime minutes for the month of November.

** Your Power Point presentation should between 4-7 pages and include the frequency distribution, charts, summary statistics and conclusions. Please use the “notes page” format to add comments and observations. **

Case 2: Consumer Price Index

Note: Although you will be studying the concept of CPI in more detail in your future ECO/561 class, for the purpose of this case, you need to use the concepts of percentages, percentage increase/decrease, and creating and interpreting line charts to compute the inflation rate in the US economy and determine which time period experienced the highest inflation rate.
