Many organizations have a multitude of data available to them but may not know what to do with these data. It is crucial to be able to study and turn data into useful information. In Week 1, you will focus on becoming comfortable with data. In your first discussion, you will look at real-world reports and begin identifying useful data points. In the second discussion, you will study data visualization techniques such as tables, charts, and graphs and learn about which ones are more effective for data displays. In your assignment, you will focus on identifying key data points in financial statements, create visuals to showcase the data, and study these visuals to find useful information.

  1. Week 1 Reflective Journal [WLOs: 2, 3] [CLOs: 1, 3, 4]. Due by Day 7. Prior to beginning work on this assignment, read Chapters 1 and 2 in Superforecasting. The intent of the journal is to apply what you have learned to how data analytics is applied in industry. After reading the assigned chapters of Superforecasting this week, write a reflective journal of the three most important take-aways contained in the chapters. Your journal should be between two to three pages excluding cover and reference page.

Turning Variables Into Knowledge [WLOs: 1, 2, 3] [CLOs: 2, 3, 5]. Due by Day 7. Prior to beginning work on this assignment, read Chapters 1 and 2 of your textbook. Imagine that you are hired as a data analyst for a bank. The bank would like to learn more about its customers’ spending and banking habits to identify areas of improvement. You have been asked to review the bank’s income statements over the last 5 years and identify trends that will allow them to better understand their customers. Download your chosen bank’s annual income statements from the last 5 years from the Mergent database in the University of Arizona Global Campus University Library. Review the Mergent Online: Accessing Mergent Online resource for tips on accessing and searching the Mergent database. Use the “Company Financials” tab in Mergent to access the income statements.

Identify three variables or categories that the bank may be interested in further researching, such as sales or revenue. Using these three variables or categories, build a frequency table, a bar chart, and a pie chart using Excel. Review the Microsoft Excel Help: BUS625 Excel Guide webpage, available in the online classroom, for resources to help utilize Microsoft Excel. You will be using the same three variables in each table and chart, so the same data will be displayed in three different formats.

After creating the three tables, which of the tables and charts do you find most useful for
communicating information about the bank’s customers? Write a brief case report summarizing your
analysis and results.
In your paper,
• Identify three variables in the income statements that the bank may be interested further
researching to learn more about its customers.
• Develop a frequency table, a bar chart, and a pie chart using variables in the income statements
for your bank.
• Analyze the table and charts to find the most useful information for communicating information
about the bank’s customers.
• Summarize your analysis and results, including how the charts were useful in your research.
