REQUIRED BOOKS
1. Business Statistics: Analytics for Decision Making (CUSTOM EDITION)
by Kvanli/Pavur/Keeling (It is a light blue paper cover = easy to recognize)
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. 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.

GOALS: At the end of the course, you should:
1. have an increased appreciation for the use of statistics in business decision making,
2. be better able to select the appropriate statistical tool/methodology to aid in business
decision making,
3. be able to use a computer spreadsheet program such as Excel to describe and analyze
numerical data,
4. be better able to communicate in the language of applied business statistics,
5. have acquired a more positive attitude towards business statistics,
6. be able to manipulate simple statistical formulae to solve non-verbal (numerical )
problems,
7. have an enhanced ability to follow directions and instructions,
8. have a much better vision of how analytics are used in analysis and business decisions,
9. understand more about job/career potential of analytics and Decision Sciences.
10. Think about becoming a Decision Sciences Major!
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:
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 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 Dec. 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
The PowerPoint lecture for each chapter is available inside Blackboard Course Content
For example, here is the lecture file for Chapter 1.
DSCI 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!
. 2. Excel Assignments: Five exercises (see pages 11 - 13) using Excel are
assigned. There will be quizzes on these Exercises to establish your point score. They will be
demonstrated in class prior to the quiz. Quizzes are in BBL (Blackboard Learn).
3. Tutorial Exercises: 15 tutorial exercises (see page 14) using the Hawkes Learning
modules are assigned. These are an important part of the course grade. The modules
will be registered online upon completion. Suggest you print out a “Certification” also.
4. Exams: There will be three exams plus a comprehensive final exam.
All exams will be closed book. For each exam, bring a formula sheet, any tables that
apply, your student ID and ID number. Old exams to review are noted above.
Point Allocation:
Exam #1 200
Exam #2 200
Exam #3 200
(Low exam of #1, #2, #3 will be thrown out) -200
Final exam (cumulative) 200
Online post-tests 100 (*)
Tutorials (Hawkes Learning) 75 (5 points each)
Excel assignment quizzes 25 (5 points each)
TOTAL 800
(*) The post-test points consist of the percentage of all answers correct, factoring in the late-quiz penalties. For example, if your correct-answer total (after late-quiz penalties) is 85 questions correct out of 100 questions asked, your post-test points are 85.
5. Grade Assignment: ≥ 90% = A ≥ 720 points
≥ 80% = B ≥ 640 points
≥ 70% = C ≥ 560 points
≥ 60% = D ≥ 480 points
Below 60% = F < 480 points
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 Dec. encounter in attempting statistics problems.
The lab is located in BLB 131 = Go visit to see where it is located. Also the UNT Learning Center is located in Sage Hall 315 and is also available to work with you.
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 Dec. not get the help you need. It is much better to
visit the stat lab as homework questions come up and not wait until the last minute.
