All course related announcements will be made through ecampus. You may access your scores here as well. Learning Objectives Identify appropriate graphs, summary statistics, and inferential statistics for real-world contexts. Interpret graphs and statistics in real-world contexts. Calculate summary and inferential statistics. Infer appropriate conclusions about populations based on data. Explain and compare properties of summary and inferential statistics. Combine concepts in new ways to solve various problems. Prerequisites Math 141 (Business Mathematics I) or MATH 166 (Topics in Contemporary Mathematics II) or equivalent. Learning to use your calculator effectively can be very helpful in solving homework problems and during exams. Required A calculator. A TI-83 is somewhat more helpful than other types of calculators. But you just need a $15 calculator that can take square roots. Textbook: The ebook version of Statistics: The Art and Science of Learning from Data, 3rd ed, by Agresti & Franklin.

In-Class Participation: (10%) There will be random quizzes conducted during the semester and you will be awarded points based on them. You WILL need to obtain an I-Clicker and REGISTER your device (https://www1.iclicker.com/register-clicker/). 2. Homework: (10%) We will have weekly homeworks that will cover the corresponding week s lecture. 3. Midterms: (60%) We will have three exams during the semester, each carrying 20% weightage. 4. Final Exam: (20%) The final will be based on the entire material. Homework There will be homeworks assigned every week that can be accessed from the Pearson website. Although discussion among fellow classmates is allowed, the homeworks you submit must be your own work. The due date for each homework may vary and will be announced at least a week before the deadline. Late submissions will not be entertained. You are strongly encouraged to utilize the Help sessions in Blocker 162 if you need help with the questions. 2
Exams For each exam you will need to bring a 8.5 11 GRAY Scantron. You can bring a calculator for numerical calculations. You may carry one-sided formula sheets for each of the exams. You will NOT BE ALLOWED extra credit projects, additional exams etc. to compensate for a poor average. Each of your THREE midterms will be 1 hr 10 mins long. These will be multiple choice exams and the dates are Thursday, February 16, Thursday, March 23 and Thursday, April 13. Midterms will be given during regular class hours (8:00 am - 9:15 am). The final (multiple choice exam) is on Friday, May 5 from 1:00pm to 3:00pm. You will need an 8.5 11 GRAY scantron for EACH exam. Coffee stained, torn and wrinkled sheet do not scan so they re NOT GRADED!!! Incompletes A temporary grade of I (Incomplete) at the end of a semester indicates that the student has completed the course with the exception of a major quiz, final exam, or other work. I shall give this grade only when the deficiency is due to an authorized absence or other cause beyond the control of the student. Copyright Notice The handouts used in this course are copyrighted. By handouts, I mean all materials generated for this class, which include but are not limited to syllabi, quizzes, exams, lab problems, in-class materials, review sheets and additional problem sets.

University Policies Academic regulations and procedures are governed by University policy. Academic dishonesty cases will be handled in accordance the University s policies. Aggie Honor System: An Aggie does not lie, cheat, steal, or tolerate those who do. Academic dishonesty includes the commission of any of the following acts: cheating, fabrication, falsfication, multiple submissions, plagiarism, complicity, and other types of misconduct. Upon accepting admission to Texas A&M University, a student immediately assumes a commitment to uphold the Honor Code, to accept responsibility for learning, and to follow the philosophy and rules of the Honor System. Students may be required to state their commitment on examinations, research papers, and other academic work. Ignorance of the rules does not exclude any member of the TAMU community from the requirements or the processes of the Honor System. Please see http://aggiehonor.tamu.edu for the complete Honor Council Rules and Procedures. Cheating is intentionally using or attempting to use unauthorized materials, information, notes, study aids or other devices or materials in any academic exercise. Unauthorized materials may include anything or anyone that gives a student assistance and has not been specifically approved in advance by the instructor. During an examination, for example, looking at another students examination or having a conversation with others is cheating unless specifically allowed in advance by the instructor. Fabrication is making up data or results, and recording or reporting them; or submitting fabricated documents. Falsification is manipulating research materials, equipment, or processes, or changing or omitting data or results such that the research is not accurately represented in the research record. The intentional invention and unauthorized alteration of any information or citation in any academic exercise; failing to acknowledge the actual source from which cited information was obtained; changing information on tests, quizzes, examinations, reports, or any other material that has been graded and resubmitting it as original for the purpose of improving the grade on that material are examples of fabrication and falsification. Plagiarism consists of passing off as ones own ideas, words, writing, etc., which belong to another. In accordance with this definition, you are committing plagiarism if you copy the work of another person and turn it in as your own, even if you should have the permission of that person. Plagiarism is 3
one of the worst academic sins, for the plagiarist destroys the trust among colleagues without which research cannot be safely communicated. If you have any questions regarding plagiarism, please consult the latest issue of the Texas A&M University Student Rules, under the section Scholastic Dishonesty. Complicity is intentionally or knowingly helping, or attempting to help, another to commit an act of academic dishonesty. Examples include knowingly allowing another to copy from ones paper during an examination or test; distributing test questions or substantive information about the test without the instructors permission; collaborating on academic work knowing that the collaboration will not be reported; taking an examination or test for another student; and conspiring or agreeing with one or more persons to commit, or attempt to commit, any act of scholastic dishonesty.
