[email protected] Office Hours: Mon, 5-6pm, Cupples I, Room 8 Course website: MyStatLab, http://pearsonmylabandmastering.com/ 1. Course Description Math 2200 is an elementary introduction to probability and statistics, including: Discrete and continuous random variables, mean and variance, hypothesis testing and confidence limits, nonparametric methods, Student's t, analysis of variance, multiple regressions, contingency tables. Software with statistical distribution functions, such as Excel, is required. You can also use more advanced statistical software, such as Stata and R, or a graphing calculator. 2. Textbook Required: DeVeaux, Velleman, and Bock, Stats: Data and Models (3rd edition) You can purchase the textbook from the bookstore for a physical copy and MyStatLab access code, or online for the code with an E-book at http://portal.mypearson.com. Optional: Craine, Smith, DeVeaux, Velleman, and Bock, Student Solutions Manual for Stats: Data and Models 3. Prerequisites The prerequisite is calculus, at the level of Math 131. If you have had or plan to take Math 132 and/or Math 233, you should consider taking Math 3200 instead. Students considering a major or minor in mathematics should certainly take Math 3200, NOT Math 2200. 4. Course Structure In the lectures I will teach new materials from the textbook. The course schedule gives you an estimate of where we will be in the book on any given day. You may come to either of the two sections if space permits, but one may run slightly ahead or behind of the other. I recommend you attend the one that you have registered for and stick with it. 5. How to study for this course? Read the relevant sections before coming to the class. Pay attention during the class and take notes. Focus on the lecture notes. Practice the homework and recommended problems.

Re-read DVB textbook after the class, since all background information needed for exams may not be presented and covered in class. Use the recommended problems to gain a though understanding of the basic concepts and to form a better expectation about exams. Nevertheless, please do not expect the exam questions to be identical to those in practice problems or to those similar courses taught previously.
5. Technology Modern statistical analysis requires computer computation tools. We will mainly use Excel for classroom demonstration; I may demonstrate regressions using Stata for several chapters in Part VI. Students may use Excel, TI-83 calculators, or more advanced software such as Stata and R. However, please do not feel obliged to use the more advanced ones; Excel should suffice. I strongly recommend that you stick with the one of your choice, so that you can focus on the learning of statistics instead of figuring out the details of operation. Although you have the choice to use different tools, you should be able to read output from any of them. The output from different tools should present the same information if executed correctly. Exam questions may contain output results and ask for interpretation. 6. Grading Policy There are four exams in this class. The three highest scores are counted; however, you are required to take all of the four exams. Your regular attendance is expected. Physical presence is important to keep the pace of learning. Random quizzes will be given as attendance checks. There are 10 homeworks in MyStatLab. Homeworks will be credited on an effort base and each homework is worth 2 credits. The total score is 100 and the breakdown is as follows: Exams: 24, 24, 24 Homeworks: 10*2 Quizzes: 8 (Given proportionally, e.g., if there are 2 quizzes, each is worth 4.) 6. Assignments and Exams Homeworks will be posted on the MyStatLab online homework system, and parallel recommended problems from the book are highlighted on the course schedule. MyStatLab let you focus on learning instead of the logistics of turning in and getting back homeworks. What’s more, MyStatLab will tell you immediately if your answers are correct and may give you hints. When you use MyStatLab, please “save” your answers. There are three evening exams and a final exam. 6. Exam Policies You will need a calculator with statistical functions (such as TI-83 or other simpler calculators), to solve the exam problems. You may bring a 3x5 card to all exams as a “cheat sheet.” Page 2 of 4
The exam dates were set by the University well in advance, and you are expected to attend them at their scheduled times. No make-up exams. Your examination room assignment will be available on the day of the exam at: http://www.math.wustl.edu/seatlookup/. After the exams, you can look up your exam scores at: http://www.math.wustl.edu/mathlookup/.
If you want some additional practice, you can find old exams from previous years at: http://wumath.wustl.edu/old_exams. Absence: If you cannot take any of the four exams, you will need to inform me in advance (at least 24 hours before the exam starts) for approval and specify the reason. I do not guarantee approval of your request. If I have approved the exception, I will compute a predicted score for this missed exam. If I determine that your request is unreasonable, you will need to go to take the exam; the score will be zero otherwise. 7. Zero Tolerance Policy on Academic Dishonesty I highly value academic honesty and have zero tolerance toward any form of academic dishonesty. I will directly report any academic dishonesty (e.g. looking over shoulder to copy from another student’s test paper during examination, etc.) to the appropriate authority without hesitation. Students who have been caught cheating in examinations will receive zero points for all examinations. In particular, “A student must not receive or provide any unauthorized assistance on an examination. During an examination a student may use only materials authorized by the faculty.” Moreover, student responsibility dictates that “If a student observes others violating this policy, he/she is strongly encouraged to report the misconduct to the instructor, to seek advice from the academic integrity officer of the school or college that offers the course in question, or to address the student(s) directly.” For the details of the policy, please refer: http://www.wustl.edu/policies/undergraduate-academic-integrity.html. 8.
