The College’s Undergraduate Committee has developed a set of learning goals and objectives that are relevant to the Core Curriculum.  It is expected that students majoring in business will be able to demonstrate competency in terms of these objectives through performance on a standardized test (ETS Field Exam—see the syllabus for MAN 4504) as well as through embedded measures throughout the curriculum.   All core-course syllabi are required to include explicit reference to the relevant goals and objectives out of this set (QMB 3250 targets those that are more quantitative in nature).  Specific goals and objectives include:


Goal 1:  Demonstrate competency in and across business disciplines

Objective A:  Demonstrate knowledge and understanding of elements of business statistics.

                        Objective B:  Demonstrate proficiency in the use of business-related software applications.


Goal 2:  Apply appropriate problem solving and decision-making skills

Objective A:  Specify and implement a framework for identifying a business problem and develop alternative solutions and a set of evaluation criteria.

Objective B:  Assess the outcomes of a course of action and make appropriate adjustments.


In this course, the abilities to memorize formulae and "crunch numbers" play minor roles.  Since computers are widely available today, it is much more important for you to be able to choose the proper procedure and interpret the results.  To accomplish these goals, we will make regular use of a statistical analysis toolkit for Microsoft Excel. 





This is the second of a two-course sequence.  You should have previously taken a statistics course that covered probability, sampling, estimation and hypothesis testing (STA 2023 or equivalent).  QMB 3250 builds on the foundation established in your introductory course and familiarizes you with using statistical procedures to make business decisions.





  • Statistics for Managers Using Microsoft Excel

  • MyStatLab for QMB3250, Fall 2011.  You will need to purchase an access code to use this site.  See the section below for where you acquire this.



You do NOT need a physical copy of the textbook.  You absolutely MUST have access to the MyStatLab website for this course because 20% of your grade will be earned on that site.   Each student must have an individual code.  They cannot be shared.  You cannot reuse the code of someone who took the course last semester.  It is possible, however, for someone who started the course last semester to use the same code if repeating the course this term.





1.      Buy a new text from one of the local bookstores, which should come with an access kit so you can log on to the textbook MyStatLab website.  The cost for this is approximately $140.  Note: if you buy a new book and don’t get the MyStatLab access kit, go back to the store!


2.      Buy just the access code online or from one of the bookstores.  On the MyStatLab site you can view the E-book version of the text.  The cost for this should be about $75.


3.      Buy a used textbook. You will still need to purchase the MyStatLab access code separately. 





1.      The first is hosted on the Sakai system.  Here you will find my lecture notes and links to the videotaped lectures, which are posted as the course proceeds.  You will also find the syllabus, information about office hours, old exams, exam room assignments and exam solutions.  Grade information will appear after each exam is scored. 


2.      The second site is the course MyStatLab site at:  http://coursecompass.com   The course ID for this term will be given on the first day of classes, when the site opens.  Here you get access to the e-version of the full textbook (all chapters including those not in our printed version).  You will also find many of the homework assignments here.  More importantly, the online quizzes are on this site.  Remember you need to purchase an access code for this.


3.      The third is the textbook companion site.  http://wps.prenhall.com/bp_levine_statsexcel_6/  This is a free site and there are several things here that you will need.  For computing, you will need either PhStat or the Excel Guide workbooks (PhStat only works on Windows PCs).  You will be analyzing some of the data that comes with the textbook, so you will want the Excel data files. Finally, some of the chapters have additional “Online Topics” that you may want to download as we get to them (the first is Chapter 8, Section 7).




We will illustrate this in class, but you need to register on the MyStatLab site to gain access.  You will either purchase a code via credit card or use the one you got with your textbook.  You will set up your user account and use your e-mail account to gain access after the first session.  Because the MyStatLab site is not run by the University of Florida, if you do not use your UF identification information, I may have trouble getting your quiz grade information transferred to the course grade book on Sakai.  The best way to prevent these problems is to:

Register on MyStatLab using your GatorLink e-mail account as your user id!

Please use your COMPLETE email account, since your gatorlink ID may already be taken.

Example:  johndoe” might already be in use within “MyStatLab” but “johndoe@ufl.edu” will most likely be available.





There will be three exams worth 100 points, with 20+ multiple choice questions. Each exam covers a specific set of topics, which are not cumulative.


On each exam, you will earn up to 5 points if you have correctly entered the identification information (name, UF ID and exam version) on your answer sheet, and have correctly recorded the code number for your assigned exam room.  It may seem silly to do this, but there are usually about 10 students that mess this up on each exam.  If the ID info is wrong, it requires tracking everything down and making a hand correction.  In that case, you won’t get those 5 points.

Individual exams will not be curved unless the class median score is below 70 percent. 


Quizzes:  There will be six quizzes administered through the course MyStatLab site.  Check the schedule for the exact due dates.  This is how I will test you on the use of the computer procedures discussed in lectures.  On the actual exams, I can have you interpret computer output but cannot test on how to perform the work.  Each quiz will be worth up to 15 points.  We will count your best 5 out of 6 scores, so collectively these will count for 75 points (20 percent of your grade). 


Homework Assignments: We will have assignments after each block of lectures, but these will not count towards your grade unless they also show up on a quiz.  Some of these assignments will appear in MyStatLab where they will receive a numerical score and can count as extra credit. 


Extra Credit, Part 1: The Marketing Department runs a series of experiments in which you can participate (details will be forthcoming).  You may use up to five of these experiments for extra credit in QMB 3250, gaining one point for each experiment.  The maximum is 5 points. 


Extra Credit, Part 2:  Each assignment in MyStatLab will be assigned a number of points.  At the end of the semester we will download your percentage score across all MyStatLab assignments.  Anyone with 30% will earn 1 point of extra credit.  Anyone with 40% will get an additional extra credit point.  Three additional points are available for 50, 60 or 70%.  The maximum is 5 points.



After the semester is over, we will take your exam scores and add them to the quiz points.  We will then add on any extra credit points you have earned, up to a maximum of 8 points.  Your total will then be expressed as a percentage of the 375 total points.  Any fractions will be rounded UP to the next whole percent (for example, 334 is 89.07% but gets scored as a 90%).  Grades will then be assigned according to the scale below.  This is the final scale - it will not change.

            A:   93% – up       B+: 87 to 89%          C+:  77 to 79%         D+:   67 to 69%

A-:  90 to 92%     B:   83 to 86%          C:    73 to 76%         D:     63 to 66%

                                                     B-:  80 to 82%         C-:   70 to 72%         D-:   60 to 62%



Students requesting classroom or accommodation on exams must first register with the Dean of Students Office.  The Dean of Students Office will provide documentation to the student who must then provide this documentation to the Instructor when requesting accommodation.




Exam 1:        Wednesday Sept. 28 (8:20 pm – 10:10 pm)                    

Exam 2:       Wednesday Nov. 2 (8:20 – 10:10pm)

Final Exam: Wednesday December 14 (5:30 pm- 7:30 pm)


Room assignments will be posted on the Sakai website about two weeks before the exam date.

NOTE:  Students in the Online Business Program will take their exams at their prearranged testing site.  The time for these may vary, so you should always check your test website several days before the exam.



These dates above are the ONLY times the exams are given, so do not ask for alternatives.  If you cannot take Exam 1 or 2 during the scheduled time, you can take the Makeup Exam 1&2.


Makeup Exam 1&2:  Monday Nov. 28 (8:20 – 10:10 pm)


I will automatically invite everyone that misses Exam 1 or 2 to the makeup, so you do not need to provide me with an excuse for missing it.   Because there is a single makeup for both exams (it will be the same one regardless of whether you missed Exam 1 or 2), the exam will cover material from the first two exams.  Note that the makeup exam is just that.  It is not meant to serve as a “do-over” for a bad Exam 1 or 2. 


You need to be careful about missing Exam 1, however.  If you miss Exam 1 and then become really ill for Exam 2 you will have to drop the course because you can only make up ONE exam.


If you miss the final exam, your makeup will be the final for next semester.  




Bring your UF ID card, at least one pencil and a pen.  You will have to show your ID, fill in your scantron in pencil, and sign your exam in ink.  If you forget your ID, you will have to turn in both your scantron and the exam, and you will not receive a score until you show me an ID in my office.


Be there, seated, at least 5 minutes early.  We will (hopefully) have double seating, so sit every other seat, starting from the aisles and working inwards.  If the room fills, take adjacent seats only in the first three rows of the room.  If you take adjacent seats in the rear you will be moved.


On exams, you may use a calculator but nothing else.   I will put a formula sheet on the exam, provide any required statistical tables and include a blank sheet for scratch paper.


It goes without saying that you cannot use cell phones, PDAs, laptops or any other devices with communications ability while you are taking an exam.  Such use will earn you a zero on the exam and you will be reported to the Dean of Students office.




With a multiple-choice exam format, it is sometimes very tempting to borrow an answer from your neighbor.  There will always be multiple versions of the exam in use, but I try hard to disguise the version. Although none of this should bother you if you are doing your own work, some students get a bit careless and misrecord the exam version identifier.  This usually results in a posted score of 4 or 5 points.  If you can show me the exam, I will be happy to correct the problem and rescore your exam against the proper key.  ALWAYS CHECK YOUR POSTED SCORE, and hang on to your exam until you are sure things worked out correctly.




If you wish to appeal the grading of an exam, you must do so by e-mail.  Clearly explain what exam question you are appealing and why you think you deserve more points.  Make sure the e-mail contains your real name, your GatorLink ID and your UF ID.  You should E-mail these to this address: mripol@ufl.edu and make sure that the subject line of the e-mail is “Exam 1 Appeal” or “Exam 2 Appeal”, etc.  Appeals submitted by any other means, or without the proper subject line, may well be ignored. 


For the first two exams, the appeal deadline is noon on the Monday after the exam is held.  For the final exam, the deadline is noon on Friday of exam week.  Late appeals will not be considered.


Be aware that there are only two types of appeals that ever get approved.  The first is if your exam was scored against the wrong key.  The second would be if the wording of a question was misleading or vague to the point that more than one answer could be considered correct.


Some things that won’t get approved are: (1) you forget to bubble in an answer or bubbled more than one; (2) you misinterpreted what the question was asking or just read it wrong; or (3) you got the right answer for the wrong statistical procedure.
