Course Description:
EC315 Quantitative Research Methods: This intermediate level statistics course covers the fundamentals of conducting quantitative research for the social and administrative sciences. The course is organized around a research project on quantitative analysis of data. Prerequisite: MA120 and CS140. 3:0:3

Educational Philosophy:
This course will be conducted in a round-table manner in which participation from students will be expected. As we discuss the various statistical concepts, we will make use of practical and familiar data so that the student will relate to said data. Be prepared to roll up your sleeves in this class as it requires that you work through "in-class" group assignments to solidify your understanding of course content.

Learning Outcomes:
  Core Learning Outcomes

  1. Derive an original regression model and run it using Microsoft Excel. Write a paper explaining this model and its outcome.
  2. Given an Excel regression output, correctly interpret the model statistics including the statistical significance of the independent variables and the R-square statistic of the model.
  3. Find the predicted value of the dependent variable given a regression output with independent variable coefficients plus values for the independent variables.
  4. Conduct hypothesis tests and confidence intervals on the mean and the difference between two means using the "t" statistic.
  5. Conduct hypothesis tests and confidence intervals on the binomial statistic and on the difference between two binomial statistics using the "t" statistic.

Core Assessment:

All Park University courses must include a core assessment that measures the course Learning Outcomes. The purpose of this assessment is to determine if expectations have been met concerning mastery of learning outcomes across all instructional modalities. For this course, the core assessment is a final exam to be administered in all sections of EC 315. This exam is worth 30 percent of the student’s final grade and will test students’ mastery of core learning outcomes through short answer questions on specific knowledge, Regression analysis procedure, and hypothesis testing.

Homework Assignments:

Your comprehension of class material, quiz and exam scores will be a direct reflection of how seriously you take your homework assignments. The problems are targeted to our discussions and will also be the basis for the quizzes, midterm and the final exam. Here are the important points to remember regarding your assignments:

  • There will be six (6) homework assignments, each worth 25 points for a total of 150 points and representing 15% of your total grade.
  • Homework will be assigned, reviewed and collected. You will receive full credit or no credit based on whether every question is completed thoroughly or not. No short answers are allowed that are void of any procedures. This will constitute an incomplete assignment and subject to the terms in the next bullet point. All questions require that you "WRITE OUT" the steps and procedures used to calculate the answers. It is impossible to answer statistics questions without having written out one or more procedures.
  • Students are to submit their assignments via the appropriate weekly "dropbox" by 5pm on Tuesday before class. Late assignment submissions will be granted on a rolling basis, meaning that 25% of the assignment's worth will be deducted for every day it is late until it is worth zero points.
  • The answer-key to the assignments will be made available by Sunday at noon. You are not to use the answer key to copy & paste, rather than to verify your own answers. No plagiarism!!
  • Absolutely no extensions will be given for assignments because you will have an entire week to complete each one. If you believe that you will have difficulty in completing any assignment, I highly recommend that you manage your weekly schedule to accommodate any unanticipated events. Also, recall that you may turn in assignments late, but you will be deducted points. In short, if you need more time, some points are better than no points.


Quizzes will consist of 20-30 multiple choice questions on the material presented during the prior session and comprises 15% of your final grade.

  • Quizzes will be available online weekly. Access to the weekly quizzes will end at 5pm on Tuesday prior to class.
  • Absolutely no extensions will be given for quizzes because you will have an entire week to complete it. Similar to your assignments, if you believe that you will have difficulty in completing any quiz, I highly recommend that you manage your weekly schedule to accommodate any unanticipated events.

Research Paper:

  • Develop a multiple regression model in which your dependent variable is explained by several independent variables.
  • A minimum of 10 pages is required, not including the title page and reference page.
  • Research thesis or proposal due the third week of class, 1/29, via its appropriate dropbox. In essence, proposal or thesis should be a rough draft of your final paper introduction.
  • Final paper is due on the last day of class, 3/5, in its appropriate dropbox. Completion of the research paper is required to complete the course and comprises 20% of your grade.
  • Refer to addendum online for information and further research paper requirements.


  • The midterm is scheduled for two hours during the fourth week of class, or 2/5, and will cover all the material through the first three weeks of the term.
  • Consists of 35 multiple choice and short-answer questions.
  • Absolutely no extensions will be given for the midterm without prior approval and evidence to support an extension.
  • Comprises 20% of your final grade.

Final Exam:

  • The final exam is scheduled for four hours on the final week of class or 3/5.
  • Will be comprehensive to the beginning of the term and consists of approximately 50-65 multiple choice and short-answer questions.
  • Absolutely no extensions will be given for the final exam without prior approval and evidence to support an extension.
  • Comprises 30% of your final grade.

The course grade for students will be based on the overall average of homework and tests taken during the course in accordance with the weighting of the various requirements as stated in the syllabus.

All final exams in all School of Business courses will be comprehensive and will be closed book and closed notes. They will constitute 30% of the total course grade and will not be a take-home exam. They will be completed during the test week in the period designated by the registrar or by the Proctor in the case online courses. If calculators are allowed, they will not be multifunctional electronic devices that include features such as: phones, cameras, instant messaging, pagers, and so forth. Electronic Computers will not be allowed on final exams unless an exception is made by the Dean of the School of Business.

Late Submission of Course Materials:
Late assignments will be deducted 25% for every day they are late.

Classroom Rules of Conduct:
Be respectful, honest and ready to learn. The use of any communication device during class will be taken as a sign of disrespect and I will reduce 5 points from your overall score for every violation. Keep in mind, I do not give warnings.
