Vast amounts of data are collected in today’s global business and economic environment. The most successful decision-makers and managers are those individuals/groups that can put this information to work effectively to guide their decision process. Accountants routinely conduct audits for their clients using statistical sampling procedures that allow them to draw a conclusion about the accuracy of the accounts receivable amount shown on a balance sheet based on the information obtained from the carefully validated sample. Financial advisors use a variety of statistical information to measure the risk associated with investments. A variety of statistical information is used in production processes to monitor the quality of the output of that process. Electronic scanners used at retail checkout counters gather data used in establishing future marketing strategies. These are but a few examples of the uses of information generated through statistical analysis of data. The first objective of the course is to familiarize you with some common statistical methods used for generating decision-making information from data. We will focus our attention on estimation and hypothesis testing, Analysis of Variance, Regression analysis and model building, forecasting with time series, and Monte Carlo simulation. We emphasize data investigation and mastering statistical reasoning, not mathematical rigor. Our approach will generally follow a three-step process: 1. PLAN Identify the question that needs to be answered. Obtain relevant data. Understand the characteristics of the data. Select a model and method. The Normal and Binomial models will be stressed because of their general applicability and ease of implementation, but they are applicable only under certain conditions. Before any calculations are performed, we must verify that the data conditions support the model. 2. CALCULATE (DO) All formulas and calculations must be understood, and therefore demonstrated and practiced, in order to use the methods properly. The computational burden will be eased in practice by the use of readily available statistical computer software. 3. COMMUNICATE (REPORT) Proper selection of the model, accurate measurement, and a correct analysis are necessary but not sufficient for the solution of management problems. The final, and most important, part is the interpretation of the results of the analysis. We will emphasize contextual communication of the results of a statistical analysis to a business audience. B. Professional appearance and conduct, effective communication, self-motivation, and team-work are as vital for ensuring success in the business environment as are strong technical skills. Inattentiveness during meetings, talking or “text-messaging” while others are speaking, and arriving late to appointments are unacceptable behaviors in the business arena. Preparing incomplete, unorganized, sloppy, and/or illegible projects will limit your promotion possibilities. Missing project deadlines will compromise your employment status. A secondary goal of the course, then, will be development of behaviors, work habits, and communication skills consistent with expectations in the business environment: 1. CITIZENSHIP Common courtesy will be extended to everyone, peers and instructors. Use of electronic devices is restricted to class related activities. 2. TEAM WORK – some graded activities will be completed in groups 3. COMMUNICATION – evaluation of written and oral expression will factor into grade determination 4. PREPARATION – research discussion topics and have appropriate materials for every “meeting” 4 BUSINESS MANAGEMENT 2320 DECISION SCIENCES: STATISTICAL TECHNIQUES Spring 2016 COURSE GRADE Determination: The class earned distribution will adhere as closely as possible to the Ohio State University recommended distribution (A = 93% and above, A- = 90% to less than 93%, etc.). Components: Item Points 5 25 30 60 200 250 MyStatLab – Lecture Prep Quizzes MyStatLab – Tests 1 Individual Case 2 Group Cases 2 Midterm Exams* Final Exam* Total Total Points 50 150 30 120 400 250 1,000 Percentage 5 15 3 12 40 25 100 *An average of 50% or higher on the exams is required to be eligible to pass the class, regardless of performance on the other components. This is a necessary, but not sufficient, requirement. You must still perform well enough on the other components to meet the class earned distribution (see above). GRADE APPEAL POLICY Although we make every effort to grade in a consistent and fair manner, occasionally an error is made or a student feels that an error has been made. Any request for re-evaluation of a grade must be submitted, in writing, within two weeks of grade availability. COMMUNICATIONS REGARDING GRADES Due to increased security concerns by the University regarding “sensitive” information, ABSOLUTELY NO student grade information will be shared via e-mail. GRADUATING SENIORS Graduating seniors must make their status known to their instructor at the beginning of the semester and follow up with a reminder during the last week of classes. ACADEMIC MISCONDUCT All material submitted for course grade credit must be your own work. Your instructor will report any suspected case to the University Academic Misconduct Committee for investigation. Past cases submitted to this group have typically resulted in the assignment of grade of E for the course plus disciplinary probation. A second offense may result in dismissal from the University. Academic misconduct is a serious threat to the integrity and value of your diploma. Such behavior is intolerable. For more information see the (revised) Code of Student Conduct, 3335-23-04 Prohibited Conduct, Part A. Academic Misconduct and Code of Student Conduct, Judicial Procedures, 3335-23-05 through 3335-2313. DISABILITY ACCOMMODATION Students with disabilities that have been certified by the Office for Disability Services will be appropriately accommodated and should inform the instructor as soon as possible of their needs. You, the student, are responsible for ensuring that your proctor form has been properly filled out, signed, and returned to the Office for Disability Services according to their scheduling requirements. If you fail to do so, and ODS will not provide proctoring for you, you will take the exam with the regular class with no special provision. The Office for Disability Services is located in 150 Pomerene Hall, 1760 Neil Avenue; telephone 292-3307, TDD 292-0901; http://www.ods.ohio-state.edu/. 5 PROCEDURE 1. Prepare for Lecture: MyStatLab Readings –assigned pages in Sharpe, et al Business Statistics (3rd Edition) MyStatLab Pre Lecture Quiz o assessment of reading comprehension o opens Sunday at 12:00 AM and closes Thursday at 7:30 AM 2. Attend Lecture: Notes are posted weekly on Carmen > SP16 BUSMGT 2320 > Content > Week # > Lecture Expand on readings Demonstrate/apply new content Videos are available to reinforce/review most course content. 3. Complete Homework: Weekly assignments given on MyStatLab. Practice is essential for developing understanding of course content, so completion of these assignments is strongly encouraged. There is no allowance for homework in the 1000 course points, but we will assign “bonus” points, up to a maximum of 30 points, for completion of the homework by the due date according to the following scale: o 3 points for earned grade ≥ 90% o 2 points for earned grade ≥ 85% but < 90% o 1 point for earned grade ≥ 80% but < 85% In order to review the HW at a later date (prep for exams, for example), you must access it and submit something prior to the scheduled close date/time. 4. Attend Recitation: Weekly materials posted on Carmen > SP16 BUSMGT 2320 > Content > Week # > Recitation Brief review/demonstration of previous week’s readings and lecture content Q-and-A Practice and/or hands-on lab. Occasional lecture. 5. Tests: Regular short tests of understanding given on MyStatLab. Individual work. No collaboration with anyone is allowed. E-text and StatCrunch available. 1 per main topic Opens Friday at 8:00 AM and closes Saturday (next day) at 11:59 PM. 6. Exams: Common Exams – notify your instructor of any conflicts immediately MAKEUPS - Missed exams can only be made-up in extreme cases (e.g., death of family member, personal hospitalization, etc.) with proper documentation (e.g., a physician’s excused absence, ER paperwork, obituary, etc.). Each decision of potentially allowing a make-up exam is made by the instructor on a case-by-case basis. Additionally, you MUST contact your instructor prior to the scheduled exam and as soon as you know of a potential problem or conflict with an exam date. Alternative methods (e.g., oral exam, essay) of testing may be used for make-up exams. If you are experiencing an extreme situation or emergency, please notify the instructor via email and/or office voice mail ASAP. (Please see page 1 of the syllabus for e-mail address and phone number.) REQUIRED MATERIALS (formula pages, probability tables) will be provided. PENCIL must be used to write the exam. CALCULATOR is necessary, but there are no restrictions/requirements regarding calculator model. NO INTERNET OR CLOUD assess is allowed. 6 7. Cases: Learning theory and techniques are necessary but not sufficient for statistical analysis in today’s business world. Statistical analysis in support of business decisions requires the manager to understand statistical software and interpret statistical results. Whether you are charged with performing the statistical analysis or not, you must be able to determine whether presented statistical results make sense and are reasonable. Detailed information will be provided for each case on Carmen > Content > Cases > Case #. Require the use of statistical computing software: Excel, Excel’s Data Analysis Add-in, StatTools, StatCrunch, Minitab, Other • • StatCrunch included in MyStatLab StatTools is available in Mason Computing Labs only o All Programs > Palisades Decision Tools > StatTools • Minitab is available in Mason Computing Labs as well as in some University settings (for example, Thompson Library, 18th Street Library) Case 1 will be completed individually, with no collaboration with any other individuals Cases 2 and 3 will be completed in groups • Teamwork: You will work with a group of your peers to complete each case. The members of each team will be determined by the instructor. • Be advised that students given low peer evaluation scores on Case 2 will be teamed together or will be assigned to complete Case 3 alone. • We cannot control when a student will drop the class or simply refuse to participate, so be prepared to solve the entire case, no matter what. Each assignment will allow you to practice and improve not only your statistical skills, but also your written communication skills. Your assignment submission should be worthy of presentation in a professional setting TIPS FOR SUCCESS IN THIS COURSE 1. Attend all lectures and recitations with a positive attitude. 2. Participate in any open discussions. 5. Take effective notes. Often times your instructor’s comments are more important than what is already printed gets written. 6. Stay current with the course material. Each week’s material builds on prior weeks’ material. 7. Form study groups. Studying with other students is definitely encouraged. Articulating the material in your own words is helpful in reviewing the lecture material, as is testing each other on content. 8. Practice as many problems as time will allow. You cannot learn to swim without getting into the water; you cannot learn to prepare gourmet meals by watching “Iron Chef;” you cannot learn statistics without putting pencil to paper – a lot! 9. Ask questions. Seek help, in class and out. 10. Communicate any problems you are having or emergencies that arise to your instructor or TA immediately. We can be of most help when asked or notified with ample lead-time. 7 Tentative Course Schedule – Spring 2016** Week Dates Topic Reading Assignment R M, 1/11 T, 1/12 Course Introduction Stat1430 Review, time permitting (Chapters 1 – 6) Chapter 7 L Th, 1/14 Review Sampling Distributions and CI Chapter 9 Chapter 11.1 – 11.3 R M, 1/18 T, 1/19 MLK Day - no classes Monday Tuesday recitations cancelled L Th, 1/21 Hypothesis Tests Part I [µ and p] M, 1/25 T, 1/26 Practice/Review – Hypothesis Testing Th, 1/28 HT Part II [µ and p] – Type I Error, Type II error, Power Key Dates 1 2 R 3 L Chapter 12.1 – 12.4 Chapter 12.5, 12.6 MyStatLab Section Test 1 Sa, 1/30 R M, 2/1 T, 2/2 Review/Practice – HT Part II L Th, 2/4 Comparing 2 populations: µ D, µ 1 – µ 2 R M, 2/8 T, 2/9 Review/Practice – Comparisons [µ D, µ 1 – µ 2 ] L Th, 2/11 Comparing 2 populations: p 1 – p 2 Chi-square Tests of Goodness-of-Fit 4 5 Chapter 13 Chapter 14.5 Chapter 14.1 – 14.4 MyStatLab Section Test 2 Sa, 2/13 6 Case #1 due at start of lecture R M, 2/15 T, 2/16 Review/Practice E W, 2/17 Midterm 1, 8:00 PM, room tba L Th, 2/18 Chi-square Test of Independence Midterm 1 Chapter 14.6 Case #2 Outline due by 11:59PM Su, 2/21 R M, 2/22 T, 2/23 Case #2 Outline Review Review/Practice L Th, 2/25 One-way ANOVA – Part I 7 Sa, 2/27 Chapter 20.1 – 20.7 MyStatLab Section Test 3 8 Week Date Topic R M, 2/29 T, 3/1 Review/Practice – ANOVA Part I L Th, 3/3 One-way ANOVA – Part II Two-way ANOVA R M, 3/7 T, 3/8 Review/Practice - ANOVA L Th, 3/10 Simple Linear Regression – Part I 8 9 Reading Assignment Key Dates Chapter 20.8, 20.10 Video supplement Chapter 15.1 – 15.2 Video Support Case #2 due at start of lecture MyStatLab Section Test 4 Sa, 3/12 Spring Break 3/14 – 3/18 No Classes 10 R M, 3/21 T, 3/22 Review/Practice M W, 3/23 Midterm 2, 8:00 PM, room tba L Th, 3/24 Review Midterm 2 SLR Part II R M, 3/28 T, 3/29 Review/Practice SLR L Th, 3/31 Simple Linear Regression – Part III 11 Midterm 2 Chapter 15.3 – 15.4 Case #3 Outline due by 11:59PM Su, 4/3 R M, 4/4 T, 4/5 Case #3 Outline Review Review/Practice SLR L Th, 4/7 Multiple Regression – Part I 12 Chapter 17.1 – 17.5 MyStatLab Section Test 5 Sa, 4/9 R M, 4/11 T, 4/12 Multicollinearity Practice/Review Chapter 18.5 L Th, 4/14 Multiple Regression – Part II Chapter 16.1–16.3, 16.6, 16.7 Chapter 18.1, 18.2, 18.6 R M, 4/18 T, 4/19 Case #Review/Practice L Th, 4/21 Forecasting with Time Series 13 14 Chapter 19 MyStatLab Section Test 6 Sa, 4/23 R M, 4/25 No classes Case #3 due details to follow FE F, 4/29 Final Exam, 8:00 PM, room tba Final Exam 15 **Homework due every Saturday at 11:59 PM. **Pre-Lecture Quiz due every Thursday at 7:30 AM, except Week 6 and Week 10 (midterm weeks).
