REQUIRED TEXTS & MATERIALS

1. Business Statistics: Analytics for Decision Making by Kvanli/Pavur/Keeling Comment: The paperback 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 (BBL) 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. After completing all the assigned homework for each chapter, you will take the chapter’s post-test in Blackboard, testing you over the assigned homework exercises of that chapter. These post-tests will be part of your final grade.

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.

2. Technology

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.

TEACHING METHOD

1. You are encouraged to pay attention to commercials and news items in printed as well as audio-visual media to become aware of the wide use of statistics in our daily lives. To better assist you in understanding the use of these methodologies in business many of the class problems will be presented as simple business cases.

2. You should work the homework exercises assigned during the course since the post-test questions refer to these assigned exercises. In addition to the problems in the textbook, the Hawkes Learning modules are intended to assist you in better structuring the learning time you spend on practice problems.

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:11. 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 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.

3. 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 supplement 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, here is the lecture file for Chapter 1.

1DSCI 2710 Course Specific Policies

1. Homework: Homework will be assigned (see page 16) 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. Note – I will review “where to start” on the homework in class.

NOTES: (1) Part of your grade will consist of the nine chapter post-tests. To take a post-test, while in Blackboard, click on Post-Tests (inside Course Content) and then click on the post-test you wish to take. For more information, see Getting Started #3 (slides 5 – 8). (2) The post-test questions are taken directly from the homework. Since the post-tests are timed, you must complete the homework assignment before taking the post-test. They are timed!

6. A Statistics Lab. is available on campus for students seeking additional help. Hours will be posted on BBL. The purpose of the lab is to assist students to overcome difficulties they may encounter in attempting statistics problems.

The lab is located in BLB 131 = Go visit to see where it is located.

Comments regarding the stat lab

1. The statistics lab is not available to aid students in taking post-test quizzes. Also note that the lab is Closed During Final Exam Week

2. (IMPORTANT) the stat lab is especially busy right before exams. There is not enough staff to handle a surge of students and so you may not get the help you need. It is much better tovisit the stat lab as homework questions come up and not wait until the last minute.
