TEXT: Elementary Statistics - A Step by Step Approach, Eighth Edition, Allan G. Bluman,
McGraw-Hill, 2012.
PREREQUISITE: Placement or one of the following MAT 092, 111, 113, 115, 121.
COURSE DESCRIPTION: Analysis of data (histograms, stem plots, measures of center and spread of a
distribution, normal distribution, scatter plots, least squares regression, correlation), producing data (design of
experiments, sampling design), probability (probability rules, random variables, probability distributions), and
statistical inference (confidence intervals, tests of significance).
COURSE OBJECTIVES: Students will develop an understanding of statistical terms and formulas relevant to
producing data, data representations and analysis concepts. They will be able to construct and analyze histograms,
stem plots, five-number summaries, box plots and scatter plots. They will be able to describe data by calculating
descriptive statistics (measures of central tendency, measures of dispersion and measures of position). They will
be able to use probability to perform hypothesis testing on sets of data, drawing conclusions based on normal and
standard normal distribution concepts and confidence intervals as well as correlation studies,
TEACHING METHODS: Concepts will be presented by methods of lecture and group discussion. Both instructor
and students will model statistical techniques. Homework exercises will include some graphing calculator exercises
involving statistical calculations, presentation and analysis. Opportunities for group and individual skill development
and problem solving will be provided. Instructor/student and student/student interaction is encouraged.

HOMEWORK/QUIZZES/FINAL EXAM: I will assign homework each class period. Homework will be
graded on “completeness” and “accuracy.” All homework problems must be worked completely to receive
all possible completeness points. Exercises selected at the professor’s discretion will be graded for
accuracy. Quizzes may be announced or unannounced. The final exam will be comprehensive. You will
frequently be asked to explain your thinking on various exercises/problems orally and in written format.
LATE ASSIGNMENTS: Any assignment turned in past the specified due date and time will receive
a grade lowered by one letter grade per each school day late.
LAST DAY TO DROP COURSE WITH A GRADE OF “W”: Feb. 27, 2014
FINAL EXAM Tuesday,April 28, 8:00-10:00am
CALCULATORS:
Each student is required to bring a graphing calculator (preferably a TI 83 or TI 84) to class each class
period and for each test. The student will not be allowed to use a cell phone application as a calculator in
class or on tests. Students will not be allowed to share a calculator during tests so put a post-it note on
your mirror stating “Take a graphing calculator to statistics class.”
This course fulfills the Mathematics General Education Requirement of the College. Assignments
in this course emphasize the General Education Program goals of North Carolina Wesleyan College.
Assignments focus on addressing critical thinking and analytical reasoning in mathematics but the course
also addresses the reading, writing and speaking goals.
CHEATING AND PLAGIARISM: A scholar is characterized by his/her honesty and fairness. Therefore,
a scholar neither gives nor receives "information illicitly with intent to deceive the instructor in his or her
effort to grade fairly any academic work" (NCWC Catalog, p.82-83). Also, a scholar does not take credit
for someone's work without giving credit to the creator. The violation of these principles is academic
dishonesty and will not be tolerated. The instructor will adhere strictly to the plagiarism and cheating
policy as stated in the 2014-2015 College Catalog.
DISABILITY SUPPORT SERVICES:
North Carolina Wesleyan College seeks to fully comply with the American Disability Act (ADA). Students
with disabilities who believe that they may need accommodations in this class are encouraged to contact
the Office of Counseling & Disability Services at 985-5369 as soon as possible to coordinate and
implement accommodations in a timely fashion. Their office location is 110A Hardee’s Building (across
from the cafeteria.) Students requesting accommodations based on a covered disability must go to the
Counseling & Disability Services Office to verify the disability before any accommodations can occur. This
is the student’s responsibility.
MATH 213: ELEMENTARY STATISTICS
A Graphing Calculator (TI-83 or TI-84 preferably) is required.

Final Exam Discussion
ATTENDANCE CONTRACT (Student Copy)
Attendance counts 5% of your final grade for the course.
You are allowed 2 absences (excused/unexcused). These are not free cuts. They are to be saved and
used for sickness or emergencies (death in family, etc.).
2 quiz/homework grades will be dropped if your number of absences stays at or below the number of
absences allowed.
Each absence above 2 absences will directly affect your final grade.
2 quiz/homework grades will not be dropped if the number of absences (for any reason) exceeds 2.
I (the professor) expect you (the student) to be in class on time and remain for class the entire period. 3
tardies will be considered one absence. Leaving class early without discussing the situation with the
professor will be considered one absence.
Attendance is critical in this course. History indicates students who cut class rarely are able to learn the
material well enough to be prepared for the next course and earn a satisfactory grade in the current
course. Do not deceive yourself into thinking you are the exception. Anything less than your best is
considered unsatisfactory!!
There will be no make-up tests or exam for unexcused absences. Make-up daily assignments should
be turned in by the next class period after the absence occurred. Make-up tests due to excused absences
should be made up immediately at the time agreed upon by the student and the professor. The professor
should be notified in advance of excused absences due to college-approved events.
An excellent, proven method you (the student) will want to use to be successful in this mathematics
course is to attend every class with completed assignments, ask questions (in class and in the professor's
office), form a study group, and study diligently for each test. Strive for understanding of concepts. When
you do not understand a concept, get help immediately. Attend tutoring sessions when needed.
Cell phones are to be neither seen nor heard in the classroom unless cell phones are being used
in a course activity. Therefore, you (the student) will attend each class with cell phones turned
off, (i.e. no sounds or vibrations). You (the student) are not to leave/return to the classroom for
cell phone use. If your (the student’s) cell phone becomes visible for any reason including ringing
during class due to a call, texting or checking messages, you (the student) will be expected to
leave the classroom and will be considered absent for that class period. Turn off your phone
immediately upon entering class and put it away so it is not visible. Exceptions will be rare and
based on extreme need as deemed by the professor.
No tobacco or tobacco products are allowed to be used in the classroom. Any student using tobacco
or tobacco products in the classroom will be expected to leave the classroom and receive an absence for
the current class period.
I (the professor) reserve the right to withdraw you (the student) from this course when unexcused
absences exceed 2 absences, according to the attendance policy outlined in the 2014-2015 College
Catalog.
I (the student) understand and agree to abide by the attendance policy as written above in order to
achieve a successful semester in this course.
