Description of MA 120 Core Assessment

One problem with multiple parts for each numbered item, except for item #3, which contains four separate problems.

1.         Compute the mean, median, mode, and standard deviation for a sample of 8 to 12 data.

2.         Compute the mean and standard deviation of a grouped frequency distribution with 4 classes.

3.         Compute the probability of four problems from among these kinds or combinations there of:

a.         the probability of an event based upon a two-dimensional table;

b.         the probability of an event that involves using the addition rule;

c.         the probability of an event that involves conditional probability;

d.         the probability of an event that involves the use of independence of events;

e.         the probability of an event based upon permutations and/or combinations;

f.          the probability of an event using the multiplication rule; or

g.         the probability of an event found by finding the probability of the complementary event.

4.         Compute probabilities associated with a binomial random variable associated with a practical situation.

5.         Compute probabilities associated with either a standard normal probability distribution or with a non-standard normal probability distribution.

6.         Compute and interpret a confidence interval for a mean and/ or for a proportion.

Class Assessment:

Tests will consist of problems selected from the homework assignments or similar problems. Although homework assignments are not graded, your success on tests will be directly proportional to the effort you put in to the homework assignments.  Each test is worth 50 points (semester total 250 points0.

Chapters 1-3    Chapters 4-5   Chapters 6-7   Chapter 8   Final (Comprehensive)

Grading will be based on performance on the four chapter tests and the comprehensive final.

Each test will be worth 50 points

The final grade will be determined based on the % of total points possible using this scale:

#### A:  90-100%    B: 80-89%   C: 70-79%   D: 60-69%   F: 0-59%

Students will start the semester with a 50 Bonus Grade.  If at the end of the semester, your bonus grade is higher than the lowest grade on a chapter test, your bonus grade will replace that lowest test grade (final exam not included)

5 Point deduction:

After the first unexcused absence, five points will be deducted for each additional unexcused absence. Absences will include tardiness or leaving the class early without permission.

3 point deductions:

Not completing class assignments. (Homework will be checked at random times during the term.)

Cell phone ringing during class.

Texting, talking or “surfing” on a cell phone or any other electronic device

Working on assignments from other classes.

Engaging in other activity that results in less than full participation in class, this includes sleeping.

Classroom Rules of Conduct:

In-class Study Time

Some classroom time may be allotted for working on assignments. This time is an opportunity for the students to get individual help from the instructor and/or fellow students. All students are expected to remain in the class during in-class study time.

Attendance

Attendance at classes is essential to successful completion of the course. Students who are absent for four consecutive class periods without legitimate reason will automatically be dropped from the course.

Students are expected to attend every class. If you know before you enroll you will not be able to make every class meeting, you should consider not enrolling in the class.

Students are responsible for learning the information missed due to an absence. Class time cannot be used for this purpose. I will be available during office hours to assist you with making up missed classes.

Tardiness not only deprives the student of valuable class time but also disrupts the learning process. Students are expected to be sitting in their chairs when class begins.

Course Topic/Dates/Assignments:
You will be provided with an assignment sheet on the first or second class meeting. The sheet will detail assignment for each class meeting during the semester, as well as test dates.

Academic integrity is the foundation of the academic community. Because each student has the primary responsibility for being academically honest, students are advised to read and understand all sections of this policy relating to standards of conduct and academic life. Park University students and faculty members are encouraged to take advantage of the University resources available for learning about academic honesty (www.park.edu/current or http://www.park.edu/faculty/).from Park University 2010-2011 Undergraduate Catalog Page 92

Plagiarism:
Plagiarism involves the use of quotations without quotation marks, the use of quotations without indication of the source, the use of another's idea without acknowledging the source, the submission of a paper, laboratory report, project, or class assignment (any portion of such) prepared by another person, or incorrect paraphrasing. from Park University 2010-2011 Undergraduate Catalog Page 92-93

Attendance Policy:
Instructors are required to maintain attendance records and to report absences via the online attendance reporting system.

1. The instructor may excuse absences for valid reasons, but missed work must be made up within the semester/term of enrollment.
2. Work missed through unexcused absences must also be made up within the semester/term of enrollment, but unexcused absences may carry further penalties.
3. In the event of two consecutive weeks of unexcused absences in a semester/term of enrollment, the student will be administratively withdrawn, resulting in a grade of "F".
4. A "Contract for Incomplete" will not be issued to a student who has unexcused or excessive absences recorded for a course.
5. Students receiving Military Tuition Assistance or Veterans Administration educational benefits must not exceed three unexcused absences in the semester/term of enrollment. Excessive absences will be reported to the appropriate agency and may result in a monetary penalty to the student.
6. Report of a "F" grade (attendance or academic) resulting from excessive absence for those students who are receiving financial assistance from agencies not mentioned in item 5 above will be reported to the appropriate agency.

Disability Guidelines:
Park University is committed to meeting the needs of all students that meet the criteria for special assistance. These guidelines are designed to supply directions to students concerning the information necessary to accomplish this goal. It is Park University's policy to comply fully with federal and state law, including Section 504 of the Rehabilitation Act of 1973 and the Americans with Disabilities Act of 1990, regarding students with disabilities. In the case of any inconsistency between these guidelines and federal and/or state law, the provisions of the law will apply. Additional information concerning Park University's policies and procedures related to disability can be found on the Park University web page: http://www.park.edu/disability .
