ATTENDANCE
Attendance at all class sessions is required. If you miss a class you are responsible for all
material covered and assignments made during that class.
GRADING POLICY
Your grade will be based on five categories: Daily Assignments, Quizzes/Weekly
Assignments, Written Assignments (2), Major Exams (2), and a Cumulative Final Exam. The
weights are as follows:
Daily Assignments
10%
There will be homework assigned for each new topic we cover. Doing these assignments
will give you the experience necessary to be successful in this course. The best way to learn
mathematics is to do mathematics. Typically, assigned problems will be due at the next class
period. Late assignments will not be accepted. At the end of the quarter, I will drop the lowest
Daily Assignment grades. Therefore, if you miss one or two, it will not hurt your grade;
however, if you miss ten or twelve, there will be an impact.
Quizzes/Weekly Assignments
10%
Quizzes and weekly assignments will account for 10% of your final grade. We will have
quizzes about once per week, typically they will not be announced in advance. They will consist of
a few problems, usually taken from homework assignments, and will serve as a means to measure
how well you are grasping the material. If you keep up with the homework and actively participate
in class meetings, you should do well on these quizzes. Make-up quizzes will not be given for
students who miss quizzes due to absence or tardy.
Each week there will be a set of problems assigned. These are in addition to Daily
Homework. These assignments will be typically given on Monday or Tuesday and will be due the
following Monday. These assignments will be graded in the same way that quizzes are graded.
These assignments represent opportunities to have additional practice with topics covered in class.
Problems on the weekly assignments may include material currently covered as well as review
material. It is acceptable (even encouraged) to work with study partners on these assignments.
Again, late assignments will not be accepted.
Again, the lowest quiz/weekly assignment score will be dropped at the end of the quarter, so
missing one will not hurt your grade at all.
Written Assignments
10%
There will be two written assignments, one after Chapter 3 and one after Chapter 9.
Details on these assignments will come at appropriate times.
Major Exams
50%
There will also be two major exams, one after Chapter 7 and one after Chapter 11. All
exams (including the Final Exam) will be open book, and calculators or laptops (with
restrictions) will also be allowed. Students will also be allowed one page of handwritten notes for
each exam. However, phones are NOT allowed. Before each Major Exam there will be an
opportunity to review concepts for the exam. All students will take the Major Exams at the
scheduled times. No make-up exams will be given. In the event that an unavoidable conflict
occurs, a grade of 0 will be given for the exam. In such a case, the grade for the Final Exam will
be used to replace a missed exam.
NOTE: Sharing of any resources (such as, but not limited to, calculators, notes,
information, pencils, erasers, …) during exams or quizzes is prohibited.
Cumulative Final Exam
20%
The cumulative final exam will account for 20% of your final grade. The
final exam will be scheduled for our last class meeting, check the Topic Outline for the date and
time. All students must take the final exam in order to receive a passing grade for the course. That
is, if you do not take the final exam, you will fail the course.
ASSIGNED GRADES
Decimal grades reported for this class will range from 4.0 to 0.0. The minimum grades that will
be assigned are as follows:
96-100%: 4.0
94-95: :3.9

SPECIAL NEEDS STATEMENT
Students with disabilities who believe they may need academic adjustments, auxiliary
aids or services to fully participate in course activities or meet course requirements are
encouraged to register with the Access and Disability Services (ADS) Office, Room A-115 in the
Administration Building. You may also call the ADS Office to make an appointment to meet
with the ADS Coordinator at (253) 840-8335 or (253)864-3301.
Students requesting accommodations must obtain the “Approved Quarterly Academic
Adjustments, Auxiliary Aids or Services” (green) form provided by ADS.
ACADEMIC INTEGRITY
It is expected that all students will follow the Pierce College Student handbook policies
corresponding to academic dishonesty and the consequences of violating those policies.
EMERGENCY PROCEDURES FOR CLASSROOMS
Call 911 and then Campus Safety in response to an imminent threat to persons or
property. In the event of an evacuation (intermittent horns & strobes), gather all personal
belongings and leave the building using the nearest available safe exit. Be prepared to be outside
for one hour and stay a minimum of 200 feet from any building or structure. So long as it is safe
to do so students are expected to stay on campus and return to class after evacuations that last
less then 15 minutes. Do not attempt to re-enter the building until instructed by an Evacuation
Director (identified by orange vests) or by three horn blasts or bell rings. Please notify the
nearest Campus Safety Officer or Evacuation Director of any one left in the building or in need
of assistance.

ADMINISTRATIVE WITHDRAWAL – NON-ATTENDANCE
Pierce College reserves the right to administratively withdraw registered
students who fail to attend initial class sessions and fail to make arrangements for excused
absences through the instructor or division dean. If a student does not make prior arrangements,
the instructor may report the students as not attending, and the student
will be dropped from the class.
If a student attends a class after being dropped, the student must follow the enrollment
policy in effect at the time, which may include a requirement for the instructor’s signature or the
payment of a late fee, as applicable.
STUDENT OUTCOMES

1. Demonstrate appropriate use of statistical terms.
2. Identify and describe various sampling methods.
3. Identify components of experimental and observational studies.

distributions), and graphs (histograms, scatterplots, and boxplots), with and without technology.
6. Interpret and analyze various representations of data.
7. Calculate measures of center (mean, median, mode) with and without technology.

21. Select and perform hypothesis tests for the mean of one population, proportion of one population,
means of two populations, and proportions of two populations.
22. Use the chi-square distribution to perform a hypothesis test such as goodness-of-fit or test of
independence.
23. Analyze two-variable data using scatter plots, linear correlation coefficients, and linear regression
lines, using technology to calculate these items.
24. Determine whether there is a statistically significant linear correlation between two variables.
Communication and General Skills
25. Communicate the results of data analysis clearly and precisely in both technical and non-technical
words, including the use of the following: correct statistical vocabulary; graphical, symbolic, and
numeric support for conclusions; indications of the strength and limitations of conclusions.
26. Engage in experiential learning of key concepts through classroom activities and/or projects.
27. Draw logical conclusions related to a specific problem by integrating the use of the following:
sampling; summary statistics and presentation of data; and either confidence intervals, hypothesis tests
or regression analysis as appropriate.
DEGREE OUTCOMES
1. Quantitative & Symbolic Reasoning
Students utilize mathematical, symbolic, logical, graphical, geometric, or statistical analysis for the
interpretation and solution of problems in the natural world and human society.
2. Critical, Creative and Reflective Thinking
Students will be able to question, search for answers and meaning, and develop ideas that lead to
action.
 Apply appropriate statistical techniques to solve problems by analyzing data and drawing
conclusions.
 Combine reason, experience, and information from this course, other courses, or earlier life
experiences to: (a) determine methods of solution for problems, then (b) apply those
methods, and finally (c) judge whether solutions are reasonable and significant.
