Spring 2017
This syllabus contains the policies and expectations I have established for STAT 1220. Please read the entire syllabus carefully before continuing in this course. These policies
and expectations are intended to create a productive learning atmosphere for all students. Unless you are prepared to abide by these policies and expectations, you risk losing
the opportunity to participate further in the course.
I will conduct this class in an atmosphere of mutual respect. I encourage your active participation in class discussions. Each of us may have strongly differing opinions on the
various topics of class discussions. The conflict of ideas is encouraged and welcome. The orderly questioning of the ideas of others, including mine, is similarly welcome.
However, I will exercise my responsibility to manage the discussions so that ideas and argument can proceed in an orderly fashion. You should expect that if your conduct
during class discussions seriously disrupts the atmosphere of mutual respect that I expect in this class, you will not be permitted to participate further.
The standards and requirements set forth in this syllabus may be modified at any time by the course instructor. Notice of such changes will be by announcement in class or by
written or email notice or by changes to this syllabus posted on the course website at http://math.uncc.edu/~dsdebruh/.
Exams
The system used to grade exams and distribute grade reports requires the use of Banner ID Number (800 number). When turning in exams, students will be required to show
their University ID (or other government issued ID) and provide their Banner ID. Failing to so will result in earning a grade of zero for that particular exam.
Each of the three midterm exams is worth a total of 100 points. There will be no makeup exams given for any reason. Period. If an exam is missed for any reason, it will
be assigned a grade of zero. All work on exams, including the FINAL EXAM, must be neat and easy to follow and answers must be clearly labeled. Otherwise, full credit will
not be obtained. No credit will be awarded for problems where more than one answer is given or the final answer is not clearly labeled. Each exam must be taken in
class on the announced day or it cannot be taken at all. Students will not be allowed to have drinks or wear hats during the exams. Also cell phones and all other electronic
devices besides an acceptable calculator must be turned off during exams. Except for multiple choice questions, all answers on all exams must be correct to four decimal
places.
Students are expected to get copies of old FINAL EXAMS either thru the instructor’s website, or one of the book stores by the second week of class. The old FINAL EXAMS
should be used to prepare for the three midterm exams and the FINAL EXAM SCHEDULED FOR Thursday, May 4, 2017 from 11:30 am to 2:30 pm.
Grading
There will be one WeBWorK homework assignment graded during the semester worth a total of 20 points, three (3) midterm exams during the semester (each worth 100
points) and a comprehensive FINAL EXAM (scheduled for Thursday, May 4, 2017 from 11:30 am to 2:30 pm) worth 125 points. The lowest score of the three midterm exams
(which does not include the Final Exam) will be dropped so the total number of points available for this class is 345. The standard 10% scale will be used to assign a course
letter grade at the end of the semester. Note that the Math Department has a policy stating that the Final Exam grade must count for approximately a third or more of the
course grade.

Grading for this course is based solely on your performance on the exams and homework. Grading is NOT BASED on your level of effort applied (inside or outside of the
classroom) to this class or your thoughts/feelings about what grade you may think you may deserve.
Calculator
Only the Texas Instruments 89 (TI-89) calculator (or equivalent) or a calculator with lesser capabilities will be allowed for use on the tests and final exam. The department
recommends the use of TI-83 or TI-84 as the instructors are equipped with these calculators. Students will be shown how to use the TI-83/84 in class. If you get any other
calculator besides one of these two, you will be responsible for learning how to use it. You should keep a backup set of batteries with your calculator. Sharing calculators
during exams will be considered cheating as will the use of calculators with higher capabilities than the TI-89. Use of calculators with internet access or the ability to store files
during the exams and final will also be considered cheating. Calculators cannot be provided by the University or the instructor.
Cell Phones and Other Electronic Devices (including iPod and tablet type devices)
Any device with internet capabilities including but not limited to, computers, cell phones, smart watches and calculators are not permitted to be used during any of the exams
or final exam.
Please make sure that cell phones are not set to go off during class (especially during exams), and iPod type (and other electronic) devices are turned off during class. This is
not expected to be a problem, however, if it does become a problem, you will be asked to leave class – even if that means turning in an exam before finishing it (WITHOUT
the opportunity to finish it later). Students will lose points on exams if his/her cell phone goes off any other type of electronic device (besides an acceptable calculator) is
used. The use of phones or any other communication device during exams will be considered cheating. Answering a phone during an exam will result in the grade being
reduced to zero (0). USE OF CAMERAS AND/OR CAMERA PHONES DURING EXAMS IS STRICTLY FORBIDDEN AND WILL BE CONSIDERED CHEATING.

Incomplete Grade
An incomplete grade will be given only in the event of serious health problems. It will not be given for the purpose of improving a grade at a later date.
Homework
There will be one on-line Homework assigned for credit and 4 other “practice” problem sets assigned in WeBWorK. The WeBWorK problems will set up around the second
or third week of class. The assignment for class credit is due Wednesday, May 3, 2017. Answers for this assignment must be submitted on-line on or before the due date.
Printed answers and late answers will not be accepted. No other homework will be assigned, however, each student is expected to work problems in the book at the end of
each section identified on the syllabus until s/he thoroughly understands the all of the material and contact the instructor with any questions about any of the course material.
Students are strongly encouraged to get the old final exams thru my website for use as study guide.
