Comment: The hard copy of this text will be used along with the electronic version available on Blackboard. The hard copy is packaged with the access code. You cannot purchase the access code separately. To access the electronic version with its supporting materials, you will need to login to your section’s Blackboard website and then provide the access code that appears inside the front cover of your textbook upon your initial use of the electronic textbook material. Do not purchase a used version of the textbook since you will be unable to take the post-tests as the access codes are designed for one-semester use in this course by each student and are not transferable.

IMPORTANT: If for any reason, you end up re-taking this course during another semester, this code will no longer be usable and you will need to purchase another code. Essentially, you are purchasing the rights to the Cengage material in Blackboard for one semester. Keep this in mind if you are deciding whether to drop the course. If you are retaking DSCI 2710 this semester, send an email to me and I will give you another textbook option. Be sure to tell when you last took the course and the instructor’s name. If you are retaking the course, you will not need to purchase another 30-character Hawkes code.

However, once you complete DSCI 2710, you will have access to the course materials in DSCI 3710 and will not be required to purchase a separate code in that course.

EXTRA CREDIT

The Honors section will employ almost all of the Hawkes Learning System (HLS) modules and the Bonus Modules will be shown in green in the HLS System.

ALTERNATIVE RESOURCES:Statistics for the Utterly Confused ; 2 nd Edition, Jaisingh, Lloyd; McGraw-Hill, Paperback, 2006.

GOALS &OBJECTIVES – HONORS STATISTICS

Develop as increased appreciation and competence in the use of statistics Create an understanding of using the concepts, methodologies and tools of statistics in the

contexts of problem definition and solution Increased attention to and discussion of topics in the context of current events Encourage creativity & innovation Encourage undergraduate research through research presentation in the coursework Encourage individual thought, presentation and writing skills in structuring and presenting

analytical analyses Application of statistics to areas of personal interest & field of study by student Innovative approaches to content, teaching and testing Emphasize development of analytical and evaluative skills through readings from primary

sources, journal articles, and other supplementary materials; Develop and interest in continued learning and development Think about becoming a Decision Sciences major!

TEACHING METHOD

1. You are encouraged to note current events, political statements, commercials and other events in your area of interest – you are encouraged to be observant of the context in which you live!

2. You should work the examples, assigned problems in the text; along with completing the Hawkes Learning tutorial assignments to grasp the basics of statistics; then think about these areas and how you might employ them in your other studies and daily life.

3. From your observations, study of the statistics area, other coursework studies and your life experience; you are encouraged to ask questions and participate in class discussions.

4. In addition to the in class testing, you will be given 1-5 problems for a take home exam; in order to give you the opportunity to expand your individual abilities to consider broader problems and provide a well structured written approach to the solution of these problems.

5. During the semester you are asked to select an area of research interest and apply one or several of the concepts, methodologies and tools you have studied during the semester. This is to be an area of interest to you; culminating in an end of semester presentation of your research work. I will discuss your area of interest with you and work with you in “sizing’ your undertaking. It is important that you learn to “scope” projects and learn to present results.

EVALUATION

To demonstrate your ability to use quantitative techniques in business, you will answer exam questions based on short cases. Rather than being purely numerical, problems will be presented in word format. In addition, you will work on Excel case studies that require you to use an Excel spreadsheet program to analyze and describe real-world business data. By simulating real business problems and requiring you to communicate in writing, using the language of statistics, these evaluation instruments will reinforce the course objectives.

General Comments:

1. Doing the assignments is essential to succeeding in this course. You are encouraged to keep up with the homework problems and check the answers to the odd-numbered exercises provided in the back of the textbook. These answers are also available in Blackboard by clicking on Course Chapters > Resources > Textbook Appendix B.

2. You should not hesitate to ask questions in class. Usually someone else has the same question, so, by asking in class, everyone can benefit from your question.

3. Regular and punctual attendance for the full period of each class is expected. Absences and tardiness is likely to cause you to miss the presentation of significant material.

Comment: If you miss a lecture, you can use the Power Points to get caught up.

4. You have the final responsibility for seeing that you properly withdraw before the scheduled last drop day. Anyone who stops attending class should execute the drop procedure since failure to do so may result in a grade of “F” which cannot be changed.

5. You are requested not to phone or email the ITDS department or the instructor for your final grade in the course. Course grades are available electronically in the week following final-exam week.

The PowerPoint Lectures

1. The PowerPoint Lectures should be used to learn the material. These lecture slides are narrated and animated. Be sure to use the Slide Show feature in PowerPoint and have your computer sound turned on.

2. The PowerPoint lecture for each chapter is available inside Blackboard Course Content For example: See below - here is the lecture file for Chapter 1.

DSCI 2710 Course Specific Policies

1. Homework: Homework will be assigned and should be completed when due. Completing the homework is critical to learning the material and completing the exams on time. You are expected to read and understand the relevant sections of the textbook. All reading material is testable, even if it is not emphasized in the lecture.

2. Computer Exercises: Five computer exercises using Excel will be assigned. There will be quizzes on these Exercises to establish your point score. The Excel assignments are not handed in.

3. Tutorial Exercises: Fifteen tutorial exercises using the Hawkes Learning modules will be assigned. These are an important part of the course grade. You will not hand in anything here; since the modules need to be registered online upon completion.

4. Exams: There will be three exams. Part of each Exam will be in class and in some cases a portion will be take home in order to utilize software in your analyses. Please begin thinking about your areas of interest for your project as soon as possible. We will discuss this more in class.
