Description
This course is a continuation of basic business statistics. Topics include hypothesis tests for one and two samples, ANOVA, correlation, simple linear regression, multiple linear regression, time series forecasting and nonparametric methods. Prerequisite: QM 2241.
Objectives
On completion of the course, the student should be able to:
1. Apply statistical hypothesis-testing and estimation for one or more populations, and interpret the results.
2. Apply ANOVA procedures to sample data, and interpret the results.
3. Apply simple and multiple linear-regression techniques and correlation analysis to sample data, and interpret the results.
4. Identify when the assumptions of parametric tests are violated and when nonparametric methods must be applied.
5. Discuss the limitations of statistical analysis.
6. Use statistical software for data analysis and interpretation of the results.
Purpose
To develop advanced statistical-analysis skills appropriate for entry-level employment in business fields. Core requirement for all undergraduate business programs. Numbered QM 2242 prior to Fall 2005.

Grading Methods: Three Midterm Exams ……………………………………….. 300 Points (total)
Class Quizzes ………………………………………………… 10 points (per quiz)
Final Exam …………………………………………………… (See note below)
Grade Structure:
A 90-100%
B 80-89%
C 70-79%
D 60-69%
F 0-59%
All three midterm exams will be given equal weight, and no additional assignments will be given to improve final grades. All grades will be “earned” by the student. If you need a particular grade in this class to graduate, keep a scholarship, be eligible for sports (or similar situations), then you will need to score high enough to earn the grade that you need. If you are having problems with this course you need to discuss this issue with the instructor at the beginning of the semester and not during finals week. It is the responsibility of the student to earn the needed grade for this class. Finally, students should have a contingency plan for computer failure that precludes completing any homework assignments in advance of the due date.
Quiz Policy: Quizzes will be administered randomly throughout the semester. Questions will be projected onto an overhead screen and students will record their answers on a 4” X 5” answer sheet. When computing the overall average, the two lowest quiz grades will be dropped. This procedure will apply to all forms of absences (excused or unexcused). Therefore, any student who misses a quiz will have the option of dropping up to two untaken quizzes.
Homework Policy: If homework is assigned during the semester. All assignments must be turned in within seven days following the date it was assigned. Assignments turned in one day late will be penalized 50% of the grade. Assignments will not be accepted after this date and students who fail to submit an assignment will receive a grade of “0” for that assignment.
Midterm Exam Policy:
Make-up exams will be given only for documented, approved absences. (See ATTENDANCE POLICY below). Make up exams are administered only to students who have received approval from the instructor prior to the test date. The make-up exam must be taken within one week of the student's return to class. Make-ups will be different from exams given in class. A grade of zero will be assigned for an exam missed due to an unexcused absence.
Use of the I-Clicker Remote:
I-Clicker Remote transmitters will be used extensively in class for the administration of quizzes and for the taking of attendance. Each student will be required to obtain his/her own personal
I-Clicker remote, transmitter. Specific ordering instructions will be presented on or before the first day of class. The approximate cost is $28.00 and all students will be required to purchase a remote for use in class in order to participate in the quizzes.
SYLLABUS INSTRUCTIONS FOR IN-CLASS (“ROLL CALL”) REGISTRATION:
An i>clicker remote is a response system that allows you to respond to questions presented during class; you will be graded on your response to quizzes and your in-class participation. In order to receive this credit, you will need to register your i>clicker remote in class. I will project a Registration screen with 3 steps to follow (look for your Troy student I.D. which will alphabetically scroll down the screen). Once your remote is registered, your [student ID] will no longer appear on that scrolling list and you are registered for the entire semester. If for some reason, you cannot follow these steps, I will need to register you during office hours on or before Jan. 19. i>clicker will be used every day in class and provide the media for the administration of quizzes. Therefore, you are responsible for bringing your remote daily." Remotes must be returned at the end of the semester. Students who fail to return their clicker at the end of the semester will be assessed a penalty equal to the cost of the clicker itself (approximately $28).
Quiz and Exam Administration:
No electronic devices other than a simple calculator will be allowed during an exam. Cell phones and translators are not acceptable calculators and are not permitted. Students will be allowed to use one 8 ½ X 11 “study guide” for each mid term exam (one side only). (Study sheets will not be permitted for quizzes . This study guide will contain any information that the student feels will help him/her on the exam. The sheet must be typed or handwritten. Xerox copies, printer copies or photo copies of presentation material are not permitted.
Final Exam Policy:
The final exam is designed to test the students overall understanding of the course material. It will consist of a very short case with approximately seven Stats II questions designed to test the student’s ability to apply the concepts of the material learned in the course. The grade for this exam will be determined as follows: The exam will begin with a short scenario and seven questions relating to the situation will be given. Students who answer 3 to 5 questions correctly will see no change in their overall average. For each incorrect answer after 5, one point will be deducted from the student’s overall average. (Example: five incorrect answers = a one point reduction in the average, 6 incorrect answers = a 2 point deduction etc;). Conversely, for each correct answer over five, the overall average will be increased by one point. Failure to take the final exam will result in a 9 point deduction from the students overall grade average.
Classroom Administration:
Students are expected to:
1. Attend all scheduled classes. Students who arrive at class after roll call may be counted absent
2. Be responsible for all instructions and assignments given in class as well as for the supporting textbook content.
3. Read the text. Read the textbook material before the lecture covering that material. This leads to a better understanding of the lecture (or lab) as well as the opportunity to ask questions about material(s) in the text that were perhaps unclear or not understood.
4. Hand in assignments on the assigned due date during roll call. See homework policy.
5. Neither hats nor sunglasses are to be worn in the classroom.
6. No food, tobacco products, nor drinks are allowed in the classroom.
7. Exam grades will be posted on Blackboard and will not be returned to the students during class. Any student who wishes to review his/her exam should do so during the instructors office hours.
8. Students who continually engage in disruptive behavior (example: excessive talking) will receive one warning with no penalty. For each successive warning a penalty of one percentage point will be deducted from the students overall average.
9. Cellular phones and beepers must be turned off prior to entering the classroom.
General Support Services:
The computer labs in 215 Bibb Graves and 249 Bibb Graves are available for student use.
Additional Services:
AMERICANS WITH DISABILITIES ACT: Any student whose disabilities fall within ADA must inform the instructor at the beginning of the term of any special needs or equipment necessary to accomplish the requirements for this course.
Students who have or may be dealing with a disability or learning difficulty should speak with the instructor, contact the Office of Adaptive Needs Program (Trojan Center 215) or call 670-3220/3221. Various accommodations are available through the Adaptive Needs Program. The faculty in the School of Business makes every effort to accommodate unique and special needs of students with respect to speech, hearing, vision, seating, or other possible disabling conditions. Please notify the instructor as soon as possible of requested accommodations or ways to help.
Attendance Policy:
1. Class Roll: Class roll will be taken at the beginning of the class session. A student who arrives after her/his name is called will be marked absent.
2. Attendance is mandatory. If a student misses a class, it is his/her responsibility to obtain all information and materials presented (including materials covered, handouts, skills learned, and homework assignments) during his/her absence.
3. Excused absences: Excused absences are defined in the following manner:
a. Professor was informed prior to the absence.
b. Professor determines that the absence is excused.
c. Excused absence will be determined according to the following criteria:
· Participation in a documented official university function that does not permit the student’s class attendance (e.g., participation in athletic events, field trips, etc.)
· Severe illness (this does not include scheduled medical appointments nor driving someone else to doctor), a hospital stay, or a doctor's excuse saying that it is impossible for student to attend class(es)
· Death of immediate family member (grandparent, parent, sibling, or child)
· Appearance in court
· Personal situations that are approved by the professor in advance of the time the student is to be absent.
Incomplete Work Policy: Any incomplete work at the end of the term will not be accepted unless the student can provide acceptable and clear documentation prior to grades being submitted to the Registrar.
Cheating Policy: If you are caught cheating, you will get a course grade of "F". See ORACLE: Student Handbook, 1998-1999" pp. 56-57. Plagiarism is the act of stealing and passing off (the ideas or words of another) as one’s own or to commit literary theft: present as new and original an idea or product derived from an existing source (Webster’s New Collegiate Dictionary). Plagiarism will cause a student to get a course grade of “F”. According to the TSU ORACLE: Student Handbook, 1998-99, pp. 52, one definition of misconduct is: “Dishonesty, such as cheating, plagiarism...” The ORACLE states on page 56 under the Academic Code sub-heading that: “A student is subject to disciplinary action:”
“Where the work affects or might affect a student’s grade, credit, or status in the university, a student represents to be his or her own any work which is not the product of his or her own study and efforts”. The penalty for such misconduct may be (pp. 56) “A student’s grade in the course or on the examination affected by the misconduct may be reduced to any extent, including a reduction to failure.” A student may be suspended from the university for a specific or an indefinite period. pp. 56-57.
