Econ 207: Business Statistics Department of Economics Minnesota State University Fall 2005 Dr. Saleheen Khan Office: 121 Morris Hall Phone: 389 2711 E-mail: saleheen.khan@mnsu.edu COURSE OBJECTIVES This course provides an introduction to theoretical and applied statistics for business and economics. The main objective is to stress the importance of applying statistical analysis to the solution of common business problems. Every opportunity is utilized to demonstrate the manner in which statistics can effectively facilitate the many decisions that business managers face on an almost daily basis. The general objective of this course is to prepare the students with skills to: (i) (ii) (iii) (iv) Develop proper understanding of conceptual framework needed for statistical analysis, Develop sound quantitative foundation for statistical analysis, Solve business related problems using appropriate statistical tools, and Use regression technique for modeling and forecasting. Upon completion of this course, you should be able to: Understand the vocabulary and methodological issues associated with presentation and analysis of data. Understand single number summary for data sets, e.g., measure of central tendency/dispersion and their use. Understand probability theory and probability distribution. Learn the properties of sampling distribution Make point and interval estimates for population means and proportion; and determine the sample size Perform tests of hypothesis about population means and proportions. Develop a model of your own using simple linear correlation and regression techniques. PREREQUISITE: Math 112 TEXTBOOK - Statistics for Business and Economics (ninth edition), Anderson, Sweeney, and (required) - Workbook ( optional, but recommended) Williams HOMEWORK Homework will be assigned regularly. Students are recommended to make a study group (each consists of 3 to 4 students) and are strongly encouraged to study together to solve homework problems. Practice is the key to be successful in taking a statistics course. Solution to the selected homework problems will be discussed in the class. You will also learn and use statistical software, SPSS, to compute statistical measures. EXAMINATION AND QUIZZES Five quizzes, two mid-term exams and a comprehensive final exam will be given in class during the semester. Exams and quizzes will consist primarily of statistical problems. A calculator will be necessary for computations. Page 2 REVIEW WORKSHEETS A review worksheet will be assigned before every major exam. You should attempt to solve all the problems in the review worksheet. It will prepare you for the exam. GRADING POLICY The total number of possible points in the course is 460. First mid-term Second mid-term Final Exam Homework Quizzes Class participation and attendance Computer Assignments : 100 pts : 100 pts : 150 pts : 20 pts : 60 pts : 10 pts : 20 pts MAKE-UP POLICY There will be no make-ups for missed quizzes regardless of reason. Please do not request me for such. Late assignments will not be accepted. Make-up exam may be given under extreme circumstances. You need to show an official, written university excuse to get that opportunity. For those with an official excuse, a single comprehensive make-up will be given during the last week of the scheduled class. Any student fail to follow this policy will receive an automatic zero for the missed exam(s). OFFICE HOURS My office hours are T – R: 12 - 4 or by appointment. I strongly encourage you to stop by my office to discuss your progress. COURSE WEBPAGE A course website has been built. I have posted review for the exams and practice exams. I plan to post more material related to the course. The website has the following URL: http://krypton.mnsu.edu/~khans3/econ207.html CLASS ATTENDANCE Regular Class attendance is essential to be successful in this class. You will be held responsible for all material presented in class, whether you are present or absent. In the event of an absence, you will need to obtain class notes/assignments for the material missed from another student before the next class. CLASSROOM POLICY I expect you to conduct yourself with professional courtesy in the classroom. You should not talk to other students during lectures unless directed to do so by the professor. Please turn off Cell Phones, Beepers, or Pagers. SPECIAL NOTE “Every attempt will be made to accommodate qualified students with disabilities.
