General Instructions For each Assignment:
1. Attach your word document for review and grading. Other file formats are not accepted and will not be graded. Use the following filename format: LastName_BUSI720_AssignmentX.docx
2. Include an APA title block with your name, class title, date, and the assignment number. 3. Include a table of contents and a reference section. Number your pages in the footer along with
the date. Include a header starting on page 2 with the Course and assignment number. 4. Write the problem number and the problem title as a level one heading (Example ‐ A.1.1:
Chapter 2, Problem 2.1, Check the Completed Questionnaires) and then provide your response. 5. Use level two headings with short titles for multi part questions (Example ‐ A1.1.a, Short Title,
A1.1.b, Short Title II, etc.) 6. Use appropriate level headings for key elements of your discussion such as Research Questions,
Hypotheses, Descriptive Statistics, Assumptions & Conditions, Interpretation, Results, and others. Your goal is to make your analysis easy to follow and logical.
7. Ensure that all tables and graphs are legible and include a figure number. 8. Carefully review your document prior to submission for formatting, flow, and readability. Keep
in mind that running the statistical tests is only the first half of the challenge; you must be able to clearly communicate your findings to the reader!
