ATTENDance policy FOR THIS COURSE:

Students are expected to attend class and be on time. Religious holidays: Please see me.

Materials/TEXT:

Elementary Statistics by Triola Edition 9 Addison-Wesley publisher

Practice homework from the text, on-line exercises, or practice tests should be done regularly. A student’s solution manual may be helpful.

The text is not required (only the class notes and calculator) IF you come to class every day.

INSTRUCTOR’S NOTES for the course are required and should be purchased from the bookstore.

A TI-83, TI-83+, or TI-84 is required. There is a calculator loan program through the library --------first come, first-served.

TESTS: If a test is missed, the student must contact the instructor or leave a message within 48 hours of the test date. Otherwise, a grade of 0 will be given. If the reason for missing the test is considered valid, a make-up test will be given. Documentation may be required. Make-up tests are more difficult than regularly scheduled tests. I expect at most one make-up exam for the course. If a class is canceled on a day when a test is scheduled, plan to take the test on the next class day.

Bonus Points

There is the possibility of getting Bonus Points for each test IF you answer a question correctly AND are on time. The Bonus Points are for a specific test; bonus points for Test1 will apply to Test1 and NOT to other tests. The Bonus Points will start on the next class and will continue on each class day. The question will be given at the very beginning of class and will be worth ½ point. There are NO make-up questions; you need to be on time. I will be rounding DOWN, so if 5 questions are answered correctly, then 2 points will be added to your test grade. The short question will be from the class before. There is a maximum of 5 bonus points for each test

PROJECTS/COMPUTER/GROUP WORK: Students will need to budget extra time outside of class. Details will be provided in writing for each assignment. I am very strict about submitting assignments on time. There are NO make-up projects.

If an emergency arises, contact the instructor via phone or email within 48 hours of the due date. Projects can be sent by email or by mail (Dr. Janice Dykacz, CCBC Essex, F423, 7201 Rossville Blvd., Baltimore, MD 21237).

COMPUTER USE: The instructor will use Minitab14 on the computer. Some projects will require Minitab, and you may need to budget extra time to use the computer outside of class. A trial30-day loan of this software may be obtained at www.minitab.com (on the left) USA go, Download menu at the top right, Minitab14 demo.

Special procedures assignments, retention of papers, compiling of portfolios, availability of support services, etc.)

Turn off pagers when you enter the classroom.

Please leave the classroom only if there is an emergency.

Please tell the instructor before class if you need to leave early.

No camera phones or other devices allowed on the test.

No exchange of papers or calculators during a test.

Rationale (Instructor’s statement relating course content to student’s personal and academic growth, etc.)

Statistics is used in a great number of areas such as business, psychology, nursing and medicine, biology, and the social sciences. This course will provide the basics of descriptive and inferential statistics so that students will be more able to read and interpret research articles in the student's field. In addition, the student should be better able to understand statistics as it is used in everyday life and in newspaper and magazine articles.

Attendance policy

Attendance at each class and lab is essential. Please be on time. Students with a legitimate problem about attendance should discuss the situation with their instructor.

NOTE: The deadline for withdrawing from a course or changing to an audit for the Spring 2006 semester is April 19, 2006. Failure to officially withdraw from a class you have stopped attending may result in an "F" grade.

COURSE REPEAT POLICY

Policy on Repeated Courses, page 194 of the 2004-2006 CCBC catalog states, “Students may repeat a course only once without permission. When a student repeats a course, only the higher grade is computed into the Quality Point Average (QPA). All grades will remain on the student’s transcript. Before a student is permitted to register for the course for a third time, the student must have the permission of the academic dean responsible for the course. Before a student may repeat a developmental course that he or she has failed twice, the student’s record must be reviewed by a support team which will make recommendations regarding enrollment.” Please note: The instructor does not have the authority to grant permission to register for a third attempt at the course.

Disabled Students

In accordance with the Americans with Disabilities Act, CCBC is committed to providing an environment that is conducive to learning for all students. Any student who is disabled and requires special accommodation should contact the appropriate campus as follows:

Campus:	Office:	Room:	Phone:
Catonsville	Office of Disabilities Support Services	K-200	410-455-4382
Dundalk	Office of Career and Life Planning	A-100	410-285-9774
Essex	Office of Special Services	A-210	410-780-6878

Code of Academic Integrity

For the College to make its maximum contribution as an institution of high learning, the entire college community must uphold high standards of integrity, honesty, and ethical behavior. In seeking the truth, in learning to think critically, and in preparing for a life of constructive service, honesty is imperative. Each student has a responsibility to submit work that is uniquely his or her own, or to provide clear and complete acknowledgement of the use of work attributable to others. To these ends, the following actions are expected of students:

· Complete all work on exams without assistance.

· Follow the professor’s instructions when completing all class assignments.

· Ask for clarification when instructions are not clear.

· Report to the instructor any unauthorized information related to an exam.

· Provide proper credit when quoting or paraphrasing.

· Submit only one’s own work.

Students who do not accept responsibility for the integrity of their own work will experience sanctions, including a written reprimand, failure of the assignment, failure of the course, and/or dismissal from the program. For repeat and extreme offenses, the College reserves the right to suspend or expel students.

Writing Policy

The College recognizes that clear, correct, and concise use of language is characteristic of an educated person. Therefore, whenever possible, faculty members in all disciplines should require written assignments in their courses in order to encourage effective writing by their students. Also, instructors should consider the quality of writing in determining a grade for a written assignment. Poor writing can be a sufficient cause for a failing grade on a paper and, in extreme cases, a failing grade in a course.

Inclement Weather/Emergency Closing Policy

In the event that the college (or a specific campus) opens late due to weather-related or other emergency conditions, classes will commence at the announced opening time and resume the normal schedule thereafter for the remainder of the day. Faculty, students, and classified staff should report to wherever they would normally have been at the announced opening time. ** CONTINUED

Students and faculty engaged in field placement programs (such as internships, clinical placements, etc.) should discuss the handling of emergency situations at the beginning of the placement period. Both the requirements of the program and the safety of persons involved should be considered in planning a course of action in those cases where students are expected to report to off-campus locations.

** For example, if you had a class that began at 9:35 and the college opened at 10:00 because of snow, you would report to your 9:35 class at 10:00.

When the college closes because of severe weather or emergency conditions, announcements of class cancellations are made on local radio and television stations and the college website (www.ccbcmd.edu). Closings and delays will also be recorded on the campus weather lines:

Catonsville	410-455-4567
Dundalk	410-282-6700
Essex	410-780-6711

TUTORING SERVICES

Students are encouraged to seek help from their instructors whenever they encounter academic difficulty (either during scheduled office hours or by appointment). In addition, each campus offers free academic support services. For more information, contact:

CIVILITY AND COMMUNITY BUILDING EXPECTATIONS

(Compassion, Appreciation, Respect, Empowerment)

As members of the CCBC community of learners, we are expected to act with respect, honesty, responsibility and accountability. Each of us is expected to be aware of the impact our behavior has on the community. CCBC wishes to each learner to commit to the following actions:

• Become an active and engaged learner

• Celebrate the richness of our diversity

• Respect the campus and its code of conduct

• Practice empathy and compassion

• Promote the empowerment of others

MAJOR RELIGIOUS HOLIDAY POLICY

Students not attending class because they are observing major religious holidays shall be given the opportunity, to the maximum extent possible, to make up, within a reasonable amount of time, any academic work or tests they miss. Arrangements between the student and the faculty member(s) for the student to make up missed assignments or tests must be made in advance of the religious holiday, at the initiation of the student.

STUDENT E-MAIL ACCOUNTS

CCBC has joined the ranks of the very few community colleges in Maryland who provide email accounts to all credit students. Each student who is registered in credit classes now has an email account and up to 5 Mb of storage in their mail box. This account will not be deleted even if the student graduates or leaves CCBC for any reason.

For information about the system and how students can determine their email address, go the CCBC Home Page and click on “Student Email”. From here students can find their email address, get to an on-line user manual and access instructions on how to forward the CCBC email to the system of choice (AOL, Comcast, Hot Mail, etc.)
