About Me:
Hello class! I’m Ms. Krieger. This is how I prefer to be addressed. I want to welcome you
all to AP Statistics. I am looking forward to getting to know each of you. Here is a little about
myself: I am from Moorhead, MN. I went to Concordia College. I majored in Math Education
and Psychology. I recently completed my Masters of Education at the University of Missouri. I
want you all to feel comfortable with me and be successful in my class. Therefore, if you ever
have any questions or need any help, please do not hesitate to come and ask me.
Textbook and Supplemental Texts:
Yates, Moore, & Starnes. The Practice of Statistics. 4th ed., W.H. Freeman & Co., 2010.
Huff, Darrell. How to Lie with Statistics
Required Materials:
three-ring binder, notebook paper, pencils, planner, TI-83/TI-84 graphing calculator, textbook
Course Description:
AP Statistics is much more than making graphs and calculating mean, median and mode.
Students in this course will learn all steps of statistical processes including conducting
experiments and simulations, analyzing and making appropriate graphical displays of collected
data, using mathematical methods to analyze the data and reaching supported conclusions about
a population or situation. In this course students will become proficient in communicating
statistical ideas with proper terminology and will participate in discussions on smart living
during an age dominated by statistics.
Course Design:
This course requires a high-level of classroom participation from each student. Students
are expected to read the chapters in the text in preparation for class. All lessons, then, are
conducted in an interactive manner that focuses on develop understanding of concepts through
investigation and discussion. Formulas, likewise, are developed through reasoning.
In this course, students first learn how to perform calculations “by hand” in order to
become familiar with complex mathematical notation and to develop a sense of the
reasonableness of answers. Students are then taught how to use the calculator applications
designed to perform the same tasks. Students are tested over both methods of calculation.

Homework assignments from the text follow the completion of the notes for each section and are
due at the beginning of the following class period. Periodically, students we be assigned reading
and response assignments from the book “How to Lie with Statistics” or statistical articles.
General Course Goals:
Students will assume responsibility for their learning by:
1. Keeping an acceptable notebook consisting of notes taken in class, homework,
handouts and graded papers.
2. Coming to class prepared with the required materials every day.
3. Completing all assignments and turning them in on time (see “Late Policy” below).
4. Reviewing class notes, reading the assigned section of the textbook and scheduling
tutoring when necessary.
5. Showing their best effort and creating a positive attitude toward learning by
participating in class and asking thoughtful questions to help enhance learning.
 All students have a TI-83/84 graphing calculator for use in class, at home, and on the AP
Exam. Students will use their graphing calculator extensively throughout the course.
 Various applets on the Internet will be used to illustrate statistical topics.
 Students will also learn how to read computer output from various statistical software

Class Activities
I expect the best out of each and every one of my students. I set my standards high for my
students because I believe everyone, if they try their best, can achieve them. It is good to set
goals and have something to work for and try to achieve. Therefore, I expect all of my students
to be doing their personal best every day.
Class Time: During class, you will engage in a variety of activities including note-taking,
mathematical discussions, and individual and group problem-solving activities. I encourage you
to raise your hand if you would like to ask or answer a question related to the material. If you do
not get a question answered in class, or have a question or comment that is not related to the
whole class, please save it and find a time to ask me when you are working independently or
after class is finished.
Homework: Homework will consist of videos or readings about the concepts we will be learning
in class the next day. This will be the “lecture” so we can spend class time practicing the
concepts in class through simulations, problem-solving, activities, and work through problems.
Therefore, daily completion of homework is required for success so you understand what we will
be practicing in class. It is expected that the assignment will be completed by the beginning of
the next class period.
Celebrations of Knowledge
Quizzes: Homework is a learning process, so I want to give you an opportunity to demonstrate
what you have learned. Occasional quizzes (announced or unannounced) will be given
throughout the course. They are meant as a check for understanding, so you will better
understand how well you know the material.
Tests: At the end of a unit, usually a test will be given. Tests will cover the material from the
unit that was just taught as well as a few possible review questions. You will usually be given
about three days notice when the test will be. The test will be in the format of an AP exam with
some multiple choice questions followed by a few free response questions.
Final Exam: There will be a cumulative final exam at the end of a semester.
Projects: You will do some projects in this course. Some projects will be done in pairs or in
small groups. The purpose of doing projects in this course is to help you get actively engaged in
the material and get creative. Math has many real world extensions and projects are a good way
to help you see some of these applications. A rubric for each project will be given to you so you
understand what is expected and how you will be evaluated for each project.

Tutoring: I am available before school, during Pride, and after school. If you schedule an
appointment with me for tutoring, please be sure that you keep your scheduled appointment. I am
more than willing to help, but please remember to let me know when you are coming so I can
make myself available!
Make-up Work: Daily attendance is extremely important in a mathematics class. You will be
held responsible for all material missed for any reason. It can be difficult for some students to
read the textbook and successfully complete the homework alone. When students are absent it is
best to plan on meeting with Ms. Krieger for help with the material. Assignments missed due to
unexpected illness or family emergency can be made up according to the handbook’s policy.
Students absent from class or extra-curricular activities are required to get the assignment early
and turn it in with their class.
Late Work: If you do not have an assignment fully completed by the time it is to be turned in at
the beginning of class you may use a “Freebie Pass”. You will get one Freebie at the beginning
of each semester. This allows you to turn in the assignment late without losing any points. If you
use your one Freebie during the semester, additional assignments that are turned in late will
receive a 0.
Absences: If you are absent on the day an assignment is due, you will be able to turn it in on the
day you return to class and not be penalized. If you are absent on the day of a quiz or test, you
will be allowed up to one day for each day absent. For instance, if you were gone Wednesday,
Thursday and Friday one week and you missed your Friday math test, you would have three days
upon your return to class on Monday to make up the exam.
Academic Integrity: I expect my students to be honest and only submit work that is their own.
If I suspect a student of cheating and/or sharing homework, school policy will be followed for
academic misconduct.
Students with Disabilities: If a student requires special accommodations due to a disability or
other circumstance arrangements will be made to help enhance that student’s learning.
Student Expectations:
Be willing. Be prepared. Be respectful.
Be responsible. Be honest.

Any student who chooses to be late or unprepared, or chooses to be disrespectful or irresponsible
will earn a warning, a phone call home, or an office referral depending on the severity of the
situation. In addition, all school policies and procedures will be followed as stated in the student
Emergency Procedures: Emergency procedures are on a sheet near the door. They follow the
procedures listed in the CIS Handbook. These emergency procedures will be practiced randomly
throughout the year. These procedures include Tornado, lockdown, and fire emergencies.
Fire drills Students must line up in the back of the room and quickly and quietly walk
out of the building. Go out the door in the back of the school and continue walking away
from the building.
Tornado drills Students will stay in the room during tornado drills.
Lockdown drills Various lockdown procedures will be practiced throughout the year.
We will have a discussion about these before and/or after the drill to be sure everyone
understands these procedures.
To parents: I am here to help your child be successful in mathematics. Please contact me
anytime if you have questions or concerns. You can reach me by phone (777-9250) or e-mail.
([email protected]). I prefer you contact me by e-mail. To see our class assignments as wells
as notes, downloads, and helpful links go to I look forward to working
with you and your child this year.
I have read and agree to follow the policies stated in this syllabus:
