Deadline
Deliverable items for the Portfolio Project will be required at different points during the course.
Details for each submission are included below in the Deliverable Descriptions.
Directions
Your bottom line is to develop a five to eight-page research paper using statistical analysis in your
research. You have recently completed your degree at Bryant & Stratton College, and have secured
an entry level professional position with an employer in your field of study. Your employer would
like you to do research and will give you latitude to develop research and find data related to your
field of study. The research must follow the data requirements detailed in the project directions, with
proper documentation for each section detailed in a Word document.
This is an opportunity for you to showcase to your employer your statistical analysis, analyzing,
and synthesis skills using Excel and Word. The results of your research should provide evidence
and persuasion for your employer to act on your research findings within your research paper.
Requirements and Formatting
Your Portfolio Project must be formatted as follows:





APA formatting
Title Page
Times New Roman or Arial 12-point font
1-inch margins
Page numbers in top right corner

Week 2
• Due by the end of Week 2 at 11:59 pm, ET.
This week you will be starting your research paper. Please submit your research file (Word doc) and
data set (please submit a screen print of your data set) in Blackboard in Week 2. Your Word doc
should be two pages in length (Page 1 – Title Page, Page 2 – Statement of the Problem).
Below are some resources on developing a Statement of the Problem:
Video: How to Write a Specific Problem Statement
ink: The Basics of Writing a Statement of the Problem for Your Research Proposal
Statement of the Problem: Based upon the data found, you must state what is the data about and
what is the intent of examining this data set. You should also answer the following questions:
1. What is the specific topic that you will research?
2. What do you hope to get from examining this data/research topic?
3. How is this related to your major?
4. What makes this data interesting to you to study?
Finding a Valid Data Set: You will need to find valid data for your project. To that end, you want to
select real data from reputable sources that relates to your degree and field of study for your
employer. You may use the provided Appendix A of websites to search for data; however, you are
not limited to using these links provided but can also utilize our Virtual Library to find scholarly
articles or research data, as well as your favorite search engine to find data you would be interested
in studying.
Week 3

Due by the end of Week 3 at 11:59 pm, ET.
This week you will be completing the below sections of your research paper as a continuation of your
research paper. Please recall that APA format has a page dedicated to any references, and all
references for the project should be placed there.
Literature Review: In this section of the paper, you will explain the purpose of your research based
on the efforts of other researchers. Using the Virtual Library or Google Scholar to find academic
papers, you should identify at least one study performed by others about your topic. After reading
your selected academic paper, you will summarize what the study is about and what the conclusions
were. Next, you should discuss how your study relates to that previous work in the field.
Below is a video reference on Literature Reviews:
Video: How to Write a Mini Literature Review
Week 4

Due by the end of Week 4 at 11:59 pm, ET.
This week you will be completing the below sections of your research paper as a continuation of your
Word document.

Goal Statement: State your research goals and objectives. To note, a goal is an overarching principle
that guides decision making. Objectives are specific, measurable steps that can be taken to meet the
goal. To help you flesh out this section, think of the following questions: What is the end goal you
are hoping this research will show? How do you plan to go about examining this? Are there certain
statistical tests you are planning on using?
Research Questions: List at minimum two research questions you would like the study to answer.
Be sure to identify any statistical variables that you will consider and their potential influence on the
other variables you identify.
Below is a video resource on Research Questions:
Video: Developing a Research Question
Methodology: During the term we studied graphs, tables, frequency distributions, measures of
central tendency and dispersion, normal distributions calculated through range, mean, standard
deviation, and z scores, regression analysis, the measurement of location, variation, probabilities,
distributions, and expectations for formulating and testing a hypothesis and interpreting the results.
For methodology, include the following:
1. Create a hypothesis from your research.
a. Use this video link as a resource: How to Formulate a Hypothesis
2. Explain how you plan to test your hypothesis
3. Identify how you plan to organize your data
4. Identify how you plan to calculate your statistical data
5. Identify how you plan to investigate associated dispersions
6. Explain if you plan to conduct a regression analysis or correlation or t-test, and the
measurements you plan to use
You will be utilizing descriptive analysis and using descriptive statistics within Data Analysis in
Excel (mean, median, standard deviation analysis, minimum, maximum). Depending on your data,
you may also be utilizing some of the following to analyze your data: (a) Correlation (b) Linear
Regression or (c) t-test.
Below are resource videos on these topics:
Correlations with Excel Video: How to Find Correlation in Excel With the Data Analysis Toolpak
Linear Regression with Excel Video: Excel – Simple Linear Regression
T-Test with Excel Video: How to Do a Two Sample T Test Paired Two Sample for Means in Excel

Week 5
• Due by the end of Week 5 at 11:59 pm, ET.
This week your analysis should be performed in Excel and documented in your research paper.
Data Analysis: Utilizing the data you have found for this project, perform all necessary analysis; this
will include any mean, variance, and standard deviation calculations, as well as any other tests you
identified in your methodology. Based on the data you have found, represent your findings through
the organizational means you identified in your methodology and be sure to include as exhibits all
