Project 4: PRO 600

Over this two-week period, you will use

math

ematical operations and data analysis to solve problems and inform decision making. Your final assignment will be the creation of a comprehensive

Excel

workbook with supporting charts and graphs and a short analysis of the data.

This project will enable you to refresh and refine your skills in math and

statistics

before you tackle a real-world data set using Excel to analyze and display the data.

Quantitative reasoning uses a process similar to the qualitative research process in that you will first identify an issue or problem and then use mathematical formulas or an analytic tool to derive a solution. You will construct graphs, charts, and tables to display data and inform analysis and interpretation. You will evaluate the results of the information, draw analyses and validate them by applying them to the issue or problem.

This project will enable you to see the connection between data and how the use of quantitative analysis of that data informs solutions to practical problems with potential impact on your organization or industry.

There are 10 steps that lead you through this project. Each step should take about two hours to complete. Begin by watching the video above, which introduces the project as it might occur in the workplace, then continue with Step 1: Refresh Your Math, Statistics, and Excel Skills.

Competencies

Your work will be evaluated using the competencies listed below.

· 1.1: Organize document or presentation clearly in a manner that promotes understanding and meets the requirements of the assignment.

· 1.2: Develop coherent paragraphs or points so that each is internally unified and so that each functions as part of the whole document or presentation.

· 1.4: Tailor communications to the audience.

· 1.5: Use sentence structure appropriate to the task, message and audience.

· 1.6: Follow conventions of Standard Written English.

· 3.1: Identify numerical or mathematical information that is relevant in a problem or situation.

· 3.2: Employ mathematical or statistical operations and data analysis techniques to arrive at a correct or optimal solution.

· 3.3: Analyze mathematical or statistical information, or the results of quantitative inquiry and manipulation of data.

· 3.4: Employ software applications and analytic tools to analyze, visualize, and present data to inform decision-making.

Step 1: Refresh Your Math, Statistics and Excel Skills

Everyone will begin this project with different background skills in math, statistics and Excel. Let’s start by thinking about what it means to engage in 

quantitative processes

 and the role these skills play in this project.

Next, assess your current baseline by refreshing your skills in math, statistics, and Excel. You will choose how much you already know and where you need to concentrate more attention in order to complete this quantitative analysis project.

After this refresher, you will create your own spreadsheet based on the template provided in the next step.

If you need help outside the classroom, you can register for the STAT 689 tutoring room (go to the Project 4 Discussion for registration information) in which you can 

access tutoring help and other resources

 to enable you to complete this project successfully. Help is free and immediate!

Step 2: Set Up Your Spreadsheet

Now that you’ve assessed and refreshed these important skills, you’re ready to begin. First 

download the Excel template

 course file and use it to 

set up your spreadsheet

. This step has you set up your basic view in preparation for the use of several tools.

After you’ve formatted and set up your basic view and saved it with your name, you’re ready to move to the next step and

add data

.

Step 3: Add Data

With your spreadsheet set up and saved with your last name, you’re ready to add data. In Section 1 on the Data page, complete each column of the spreadsheet to arrive at the desired calculations.

When you’re ready, move on to the next step, where you will use functions to

summarize the data

.

Step 4: Use Functions to Summarize the Data

With your data built, you are now ready to start using some tools to summarize the data, using Countif and the Sum function to do the math. In this step, you’ll begin to see patterns in the data and the story of the workforce.

Take a breather here if you need it. You should strive to work through the first four steps this week. Check in with your instructor.

With this step complete, you’re ready to begin your analysis.

Step 5: Analyze the Workforce

You’ve summarized the data. Next, you will employ 

descriptive or summary statistics

 to analyze the workforce. Your summary tables described “how many.” Now you will 

calculate mean, median, and mode for the categories of data, and derive the deviation, variance, and dispersion, and distribution

. This is where it gets interesting!

You will be working in section 3 of the Data tab in the spreadsheet to complete the descriptive statistics for the five categories (Salary, Hourly Rate, Years of Service, Education, and Age). Using Excel formulas, complete the table.

After you have used Excel formulas to find this information, you will next use the Toolpak to find your summary statistics.

Step 6: Use the Analysis Toolpak

Your data set is now built. Now, you will use the same functions to perform the 

Descriptive Analysis Using the Analysis Toolpak

. This is a handy feature to know. Remember that there may be some minor differences in the answers depending on the version.

You should now have Tab 2 complete: Excel Summary Stats. Next, you’ll create charts and a histogram for Tabs 3 and 4.

Step 7: Create Charts and a Histogram

Where would we be without the ability to view data in charts? It is sometimes easier to grasp context of data if we can see it captured in an image. In this step, you will 

work with data to create charts

, adding a tab for charts, and another for a histogram.

In this step, you will build Tab 3: Graphs—Charts and Tab 4: Histogram. After you complete these tabs, you’ll be ready to sort the data.

Step 8: Copy and Sort the Data

You’ve accomplished a lot with your data set, summary stats, charts, and histograms. Another skill you’ll need to be able to do is sort data in an Excel worksheet for reporting purposes. You’ll 

copy and sort the data

. This is a good skill that applies to any Excel application.

In this step, you will create Tab 5: Sorted Data. When you’re finished, you’ll be ready to conduct your quantitative analysis.

Step 9: Conduct Quantitative Analysis

In this step, your hard work bears fruit. What does it all mean? Think back to your boss’s reasons for tasking you with this project. Bring your powers of analysis to bear to determine what the data may be telling you. Apply your quantitative reasoning skills by answering the questions provided in the resource and writing a short essay.

After you answer the questions, your short essay should include:

· a one-paragraph narrative summary of your findings, describing patterns of interest

· an explanation of the potential relevance of such patterns

· a description of how you would investigate further to determine if your results could be perceived as good or bad for the company.

You will prepare your responses in your workbook on the tab named QR Analysis. Type in your answers to the questions as well as the final essay in the textbox, and move the QR tab to the first tab position ( to the left of the Data tab) when you have finished.

Step 10: Submit Your Completed Workbook and Analysis

You’re now ready to submit your workbook and analysis. Review the requirements for the final deliverable to be sure you have:

1. Excel Workbook with Six Tabs

· Tab 1: Data—completed data sheet (Steps 1–6 above)

· Tab 2: Excel Summary Stats (Step 6)

· Tab 3: Graphs—Charts (Step 7)

· Tab 4: Histogram (Step 7)

· Tab 5: Sorted Data (Step 8)
Quantitative Analysis (Step 9; see detail below and move to first position upon completion.)

2. Answers to Questions and Short Essay

Prepare your response in this workbook. Create a tab for Quantitative Analysis, create a text box, and paste your answers to the questions and your essay in it. Move the Quantitative Analysis tab to the first tab position.

Make sure the following tabs are included in your final workbook:

· Quantitative Analysis

· Data

· Excel Summary Stats

· Graphs–Charts

· Histogram

· Sorted Data

3. Format to Be Printed

Format this workbook so that all the spreadsheets can be printed.
