STAT 100, Section 004: Statistical Concepts and Reasoning
Fall 2012
This online document is the official course syllabus.

You may download a pdf version of this syllabus if you wish.
Welcome to STAT 100! Statistics is the art and science of extracting information from data
concerning a question or hypothesis of interest. The objective of this course is to introduce the student
to statistical reasoning and interpretation of data analysis.
Required Textbook: Seeing Through Statistics, Third Edition, by Jessica Utts, published by Duxbury
Press. We will cover most of this book; see the tentative calendar below. You will probably not need
the CD-ROM that comes with the book, so feel free to buy a used copy.
i>clicker also required: You will need an i>clicker, available at the student bookstore. Please note:
You should not buy an i>clicker2 or an i>clicker+, only the original i>clicker. If you already have a
clicker that you use for another class, you may use the same one for this class. Important: If you have
not yet done so, you must register your i>clicker so that you get credit for your work in class. The
easiest way to do this is by visiting the ANGEL site for this class and clicking on Lessons->Register
Your Clicker, then following the instructions.
Schedule: MWF 3:35-4:25 in 101 Thomas
Course Website: www.stat.psu.edu/~dhunter/100
Instructor: David Hunter (http://www.stat.psu.edu/~dhunter). Email is the best method of contact:
dhunter@stat.psu.edu
Office hours: Shared office hours for all introductory statistics courses will be held 25 hours per week
in room 7B Sparks during the following times:
Sunday through Thursday, 7:00pm to 9:00
Monday, Tuesday, and Friday, 10:00am to 1:00pm
Wednesday and Thursday, 1:00pm to 4:00pm
Prof. Hunter's office hours will be Fridays, 8:30 to 11:30, 326A Thomas Building.
Required Work: There will be a total of 500 points awarded in the course, consisting of:
1. Three in-class mid-semester examinations, each worth 100 points. (See "Exams" below)
2. Ten randomly timed, in-class quizzes, each worth 5 points. (See "Quizzes" below)
3. A comprehensive final exam, worth 150 points. (See "Exams" below)
Final Grades: Final letter grades will be determined as follows:
B+: 88-89% C+: 78-79%
A : 94-100% B : 84-87% C : 70-77% D : 60-69%
A-: 90-93% B-: 80-83%

STAT 100, Section 004, Fall 2012: Course Syllabus
http://sites.stat.psu.edu/~dhunter/100/syllabus.html
Exams: All exams will be in multiple-choice format and will use computer scan-tron (bubble) sheets.
To each exam, you should bring:
1. A single 8.5 x 11 inch sheet of formulas or notes (double-sided if you wish),
2. No. 2 pencils to complete your scan-tron sheet, and
3. Your Penn State University student ID card.
You may bring calculators but generally you will not need them. See also "Course Rules" below.
Quizzes: At least 13 randomly timed, in-class quizzes will be given, and your best 10 scores will
count toward the final score. Each quiz is worth 5 points and it will use the clickers. It is to your
advantage to attend class regularly throughout the semester. See also "Course Rules" below.
Extra credit: There will be occasional chances to earn one point of extra credit for completing small
assignments. These opportunities will be announced as they occur.
Homework: Homework will be assigned but not collected. Answers to some homework assignments
are posted on the course web page. The exams and quizzes will reflect the homework assignments, so
it is advantageous to do your homework diligently.
Course Rules:
1. No late or make-up exams will be given. If you must miss any exam, you should provide a valid
reason IN WRITING to the instructor PRIOR TO THE EXAM. If you have to miss an exam at
the last minute for some reason, be sure to notify the instructor prior to the exam time by email
or by leaving a phone message; in these cases, you should later back up your excuse with
written documentation. Once the instructor has approved your written excuse, your final grade
will be calculated without the missed exam (e.g., if you miss one of the midterms, then your
final grade will be calculated based on 400 total points instead of 500).
2. No make-up quizzes will be given for ANY reason. You will be allowed to drop at least three
quiz grades, which should cover any excused absences that may result in a missed quiz.
3. Students are responsible for all announcements and supplements given within any lecture.
4. If you need to leave class early, please sit in the rear and leave as quietly as possible.
5. Please be courteous to your classmates and keep extra noise to a minimum.
6. Please turn off all cell phones and pagers during class.
Academic Integrity: All Penn State and Eberly College of Science policies regarding academic
integrity apply to this course. See http://www.science.psu.edu/academic/Integrity/index.html for
details. Please understand that the integrity policy also applies to the use of clickers. In particular, use
of any clicker by someone other than a person to whom it is registered is a violation of the policy and
will result in academic sanctions such as a loss of five or more points from the final course grade,
depending on the severity of the violation. Basically, to avoid problems, you should never bring any
clicker to class that is not your own.
Code of Mutual Respect: The Eberly College of Science Code of Mutual Respect and Cooperation
(www.science.psu.edu/climate/Code-of-Mutual-Respect final.pdf embodies the values that we hope
our faculty, staff, and students possess and will endorse to make the Eberly College of Science a place
where every individual feels respected and valued, as well as challenged and rewarded.
