Program Learning Outcomes This course directly supports the Effective Analytical Problem Solving Goal in the Romain College of Business.
Textbooks and/or Course Materials Access to MyStatLab (MSL) is required. ISBN:9780321694645
(NOTE: if you purchase the materials through the bookstore you will be purchasing the access
code. If you purchase an access code online it may not give you access to the materials for this
course.)
The access code is linked to the following book: Statistics: The Art and Science of Learning from Data. Fourth Edition. Agresti, Franklin, and Klingenberg, 2017.
The e-version of the book – that comes with the MSL code is acceptable. If you prefer a hard copy you may purchase it for an additional fee. See “Purchase Options” on the MSL menu. Additional readings will be posted in Blackboard and assigned as appropriate. JMP – this software will be available both in our classroom and in the computer lab in the BEC. You may also have it installed on your own computer for free. You are not required to have JMP installed on your own computer, although it is recommended. To have JMP installed on your own computer go to MyUSI, click on the JMP tab and follow the instructions.
Please read ALL of the instructions and follow them. Note – installation is slightly different for MAC than for Windows. MAC installation requires you to get the license as a separate step. So plan accordingly. Any issues with downloading the software should be directed to Juzar Ahmed in IT. His contact information is: Liberal Arts Center 0116 Phone: 812-465-7160 Email: [email protected]
Blackboard Course Site Overview Many of the course materials are provided through the course Blackboard site. The first four buttons in the menu list are for the Homepage, Tools, Instructor and Tutor Info, and Syllabus.
The Tools button leads to a list of tools available for the course – with the most important one
being the link to the Pearson MyStatLab and Mastering course. Clicking on that link will take
you to the MyStatLab course. YOU DO NOT NEED A COURSE ID FOR ACCESS.
The Content folder will contain many support materials as the semester progresses.
The JMP Assignments folder will contain those assignments, as well as any datasets or support
materials needed for those assignments.
Data Files folder contains many datasets we will use in class and that you can use on your own
to review concepts. Data files for the JMP assignments will be placed in the assignment folder.
Minimum Technical Skills
Be able to navigate Blackboard.
Be able to navigate the MyStatLab course.
Be able to use basic Word, Powerpoint and Excel functionality
Be able to access your One Drive in Office 365 and our shared folder in One Drive
Be able to do basic arithmetic.
Be able to connect to Zoom meeting room as necessary.
Assessments MyStatLab (MSL) Assignments:
These online assignments will be due on Thursdays at 11:59 pm (but not every Thursday).
MSL will be accessed through Blackboard – so no need for the Course ID.
Late assignments completed within one week of due date/time will receive a 50% penalty.
MSL assignments submitted more than a week late will receive no credit.
It is the student’s responsibility to be aware of and meet these deadlines.
JMP Assignments:
Primarily problem solving activities.
Assignments will be posted in Blackboard (Bb).
Will require use of JMP (and possibly other technology).
Most will require you to print them and hand in during class. See the rubric for specific instructions.
On occasion an assignment may require uploading to Bb.
If you need to turn in an assignment outside of class you will need to make arrangements ahead of time – do not just email them or slide them under the door.
It will be your responsibility to get the homework completed AND submitted appropriately by the deadline.
Computer issues are not an excuse for not completing the homework and will not be granted a deadline extension. This includes issues uploading to Blackboard.
Follow the instructions in grading rubric for full credit. (Rubric attached to this document and found in Bb.)
May be done individually or as a group: o No more than 4 people per group. o Everyone gets the same grade. o Everyone in group must contribute. o Groups are not permanent – if your group did not work well the first time you are not
obligated to participate in the group again. o If someone asks to be added to your work without contributing tell them NO!
Exams:
Exam dates are listed in the course schedule below.
All lectures and assignments – homework, in class activities and reading - will be covered on exams
Each exam will be primarily problem solving (including using JMP and/or Excel) and may also be comprised of multiple choice questions and/or short answer questions.
All exams are cumulative.
No make-up exams will be given. If you know ahead of time you cannot make an exam due to a University or job commitment then you can take that exam early.
No exams will be given later than the rest of the class.
Unless you have a documented disability and use the Office of Disability Resources (ODR) no extra time will be given for exams.
Plan ahead - you may not leave the classroom during an exam – including the final exam.
No memorization is required for the course – a “formula sheet” may be used for each exam.
As per University policy, final exams will not be rescheduled unless you have four finals scheduled for the same day. Make sure you have cleared your calendar for your scheduled exam times.
Comprehensive Final Exam
See Late Assignment/Exam Policy in Course & University Policies Section of this syllabus. Bonus Points: There will be 3 opportunities for bonus points throughout the semester:
Complete and submit (in Bb) the Week 1 checklist by Sunday, August 26th at 11:59 pm.
Miss no more than 1 class in the first 6 weeks. (The ONLY excused absences are for University
required commitments such as sports teams, academic teams, etc.)
Thorough and complete notes. Make an appointment with instructor to have notes checked
anytime between November 19th and December 3rd. See Blackboard Bonus Points Folder for
details.
Grading Methods Approximate Evaluation: Midterms 150 points (2 midterms/75 points each) MSL Homework 150 points (10 assignments/15 points each) JMP Assignments 250 points (6 assignments/50 points each/lowest score dropped) Bonus Points 15 points (3 opportunities/5 points each) Final Exam (Comprehensive) 150 points Total (Approx.) 700 points Grading Scale:
A 90% and above B 80% - 89% C 70% - 79% D 60% - 69% F Below 60%
The final course grade is assigned based on the percentage of total points available. NO ROUNDING will be done. That means that 79.6% is a C, not a B.
Communication Guidelines
Communication Expectation
The best way to contact the instructor with questions, concerns or for additional assistance is through email. The instructor will respond as quickly as possible and except for unusual circumstances within 24 hours. Plan ahead on due dates and times. Emails received close to the due date and time may not be responded to until the deadline has passed.
Netiquette
All class communications and interactions with other students and the professor should follow
common social standards for respect and courtesy. Learn about the USI Netiquette Guidelines
for Online Students so that you can get the most out of your class.
Student Responsibilities Classroom Etiquette:
Professional behavior is required.
Be on time. If for some reason you must come to class late or leave early please minimize the disturbance to the rest of the class.
Once class has started please do not leave the room. This is very distracting to everyone else.
All electronic equipment must be turned off or in silent mode during class.
Computer use is for work related to class ONLY and will only be used when the entire class is doing a computer activity.
NO TEXTING is permitted.
You are expected to be engaged in the class – ask relevant questions, answer questions, participate in discussions.
Past history indicates that students with poor classroom etiquette tend to perform poorly in the course.
Time Commitment:
Plan to spend 2 – 3 hours on each MSL assignment.
Plan to spend 4 – 6 hours on each JMP assignment.
NOTE: there will be a significant time commitment required on weeks where both an MSL and a
JMP assignment are due. That will only be challenging if students leave both until the last
minute.
Plan to spend 1 – 2 hours per week reading the book and reviewing notes between classes.
Course Timetable See pages 11 and 12 for the course outline and schedule.
Course & University Policies
Late Assignment Policy
MyStatLab assignments can be completed late but must be completed (for partial credit) within
one week of the due date/time. These will receive a 50% penalty. (Note partially completed
MyStatLab assignments will still receive credit.)
JMP assignments may NOT be turned in late – NO EXCEPTIONS. Since the lowest JMP score will
be dropped there is no grade penalty for not submitting one assignment.
Technical issues are not a valid reason for turning in late work. PLAN AHEAD.
In case of Missed Exam:
You can request that the final exam be counted twice – once for the final exam grade and once (prorated) for the midterm exam grade.
The request must be in writing and made within 1 week of the scheduled exam.
If the request is not made you will be given a 0 for the missed exam.
You may only substitute the final exam grade for one midterm grade. If more than one midterm exam is missed you will get a 0 for the other midterm that was missed.
The final exam schedule can be found at: www.usi.edu/registrar/classes/final-exam-schedule
Withdrawal Policy:
LAST DAY TO WITHDRAW WITHOUT EVALUATION IS FRIDAY, October 19th.
WITHDRAW WITH EVALUATION – after October 19th:
Officially, the last day to withdraw from this class is Wednesday, December 5th – which is the day before final exams begin. I will be happy to sign a drop slip up to and including that date as long as we have discussed the possibility previously – in person.
I reserve the right to assign a grade of F to any student whose drop slip is not signed by me personally.
If you stop coming to class you will receive an F – no drop slip will be signed.
There are financial considerations for withdrawals and the Financial Aid Office and Student Accounts should be consulted to determine financial ramifications.
Communications:
Check your USI email frequently as this will be my main communication tool.
Support materials will be posted in Blackboard so check it frequently.
No grade information will be communicated via email.
Per USI policy – only USI email addresses will be responded to.
Emails will be responded to as soon as possible – but on occasion may require up to 24 hours for response.
In keeping with the Romain College of Business goal to develop professional communication skills you must use business-like writing in your emails.
Grade issues must be discussed in person, in my office.
Disputed grades must be addressed within a week of the grade posting in Blackboard.
Attendance Policy:
Attendance will be taken for the first 6 weeks.
Students whose attendance is a problem in the first three weeks of the course will be reported as non-attending. (Note: Missing even one class that early in the semester is a warning sign.)
Students whose attendance is a problem during the first six weeks of the course will be administratively withdrawn from the course.
Due to the nature of this course students will find class attendance and engagement a necessary condition for satisfactory performance.
You only need to contact me if you will miss a significant amount of class time (for instance, surgery or major illness). PLEASE DO NOT EMAIL ME ABOUT MISSING AN INDIVIDUAL CLASS DAY.
If you miss class you must make up the material since all material builds on previous concepts.
The only excused absences will be for University related events – sports teams, academic teams, conference attendance, etc. All other absences will count toward your absence total.
Academic Integrity Students are expected to maintain complete honesty and integrity in the academic experiences both in and out of the classroom. Any student found guilty of dishonesty including, but not limited to, plagiarism and/or cheating on an examination will be subject to disciplinary action.

Students who receive an accommodation letter from Disability Resources are encouraged to discuss the provisions of those accommodations with their professors before or during the first week of the semester. If you will be in an internship, field, clinical, student teaching, or other off-campus setting this semester please note that approved academic accommodations may not apply. Please contact
Disability Resources as soon as possible to discuss accommodations needed for access while in this setting. For more information, please visit the Disability Resources website.
Class Withdrawal & Incomplete Policy It is the student’s responsibility to officially drop/withdraw from any courses before the deadline. The university does not withdraw students from any classes. Please refer to the USI Academic Calendar (https://www.usi.edu/registrar/academic-calendar) for specific dates. For more information, please visit Registrar’s Office Schedule Changes Under special circumstances, students may petition for an incomplete grade. However, it is up to the course instructor to decide if an incomplete will be granted. Students receiving an incomplete grade will need to complete all course requirements by the agreed deadline to avoid an “F” grade.
Title IX, Sexual Assault and Gender Violence Policy USI does not tolerate acts of sexual misconduct, including sexual harassment and all forms of sexual violence. If you have experienced sexual misconduct, or know someone who has, the University can help. It is important to know that federal regulations and University policy require faculty to promptly report incidences of potential sexual misconduct known to them to the Title IX Coordinator to ensure that appropriate measures are taken and resources are made available. The University will work with you to protect your privacy by sharing information with only those who need to know to ensure we can respond and assist.

Fall 2018 JMP Assignment Rubric
Each JMP assignment will be graded on four goals: Completeness, Support of answers, Accuracy of answers and Professional Style.
= Did a good job completing goal ~ = Somewhat completed goal X = Did not complete goal
Goals: 1. Completeness:
Every part of every question completed in an appropriate and reasonable manner.
Submitted on time and as instructed. 2. Support of answers:
All relevant JMP output, formulas, and calculations included. 3. Accuracy of answers:
Correct answers – both numeric and written answers.
Correct output 4. Professional Style:
The document must be saved in Microsoft Word
The document must have a title page that includes names of all group members (or the individual), class name – including section number, date of submission and homework name (for instance JMP Assignment 1).
If turned in as hard copy the document MUST be stapled
If turned in through Blackboard the Word document must be uploaded appropriately by the deadline.
Double space between questions and question parts.
Output must be sized appropriately – meaning output is readable and does not extend across page breaks
Tables and charts must have a title following APA style guidelines. (See reference in Blackboard.)
Answers must be easily seen in the document
Late Work: No late JMP assignments will be accepted.
Academic Dishonesty: Submitting homework that is not your own work is considered academic dishonesty. It will
receive a grade of 0 and will be reported through the official academic dishonesty system.
If you choose to work in a group everyone in the group must contribute to the assignment. DO
NOT ask your peers to add you to their work.
Correct output will all be the same – however, similar (unusual) formatting is an indicator of
academic dishonesty.
Output will be the same – words will not. Changing a few words in a sentence is still academic
dishonesty and will be dealt with accordingly.
Sharing files with those outside of your group is automatically considered academic dishonesty
and will be treated as academic dishonesty.
NOTE: If done as a group no more than 4 people may be in the group. Each person listed on the document must actually contribute to the work. Do not ask your peers to include you if you have not contributed.
