Course Description:
The applied use of statistics in the natural sciences. This course will proved an overview of statistics important to biological investigation, hypothesis testing, sampling protocol, and experimental design. Emphasis will be placed on computer statistical packages, natural science data, and application and interpretation of these statistics. Students will be introduced to several common statistical tests, including one- and two-sample hypothesis testing, analysis of variance (ANOVA), correlation, regression, and chi-squared tests with nonparamentric alternatives briefly discussed. Prerequisite: MA 131 or higher. 3:0:3

  Instructor Learning Outcomes

  1. Define basic terms in statistics and recognize problems inherent in using statistics in natural sciences including the difference betwee parametric and nonparametric statistics (key discipline topics, discipline terminology)
  2. Use several computer-based statistical packages (currently Excel and SPSS) (technical skill, discipline concepts)
  3. Analyze and interpret results of various data sets using t-tests, ANOVAs, regresions, contingency tables, and several of their variations (critical thinking, communication, essential technical skill)
  4. Design experiments in the natural sciences using a variety of experimental designs, research methods, and statistics and prepare methods of analytical research in written format (critical and creative thinking, essential technical skill, communication)
Class Assessment:
The teaching techniques utilized in this course include: traditional lectures by the instructor, small group discussions, and laboratory application of material learned in lecture. Student preparedness for lecture will be measured through the periodic administration of "pop" quizzes. The student's overall command of statistics will be measured with two regular examinations and a comprehensive final over lecture material. The examinations will be composed of short answer, matching, solving word problems and short essays.
All course announcements and links to resources will be made using the eCompanion website for the course.


The following weights will be applied to course assignments:

Examinations - 30%
Final Examination (Core Assessment) - 25%
Homework - 35%
Periodic Quizzes - 10%


The grading scale for this class is:

100-90 = A (4.0 honor points)
89+-80 = B (3.0 honor points)
79+-70 = C (2.0 honor points)
69+-60 = D (1.0 honor point)
Below 60 = F (no honor points)

Late Submission of Course Materials:

Unless announced otherwise, homework is due at the start of the assigned class period. Homework turned in after roll is taken is late. Late homework will be reduced in credit by 25% for each day or part of day that the work is late. Students missing class due to participation in athletic or other school-sponsored events must turn in all homework PRIOR to their absence. Exceptions: students who miss class due to an extended illness requiring hospitalization will be allowed to make up missed homework assignments. Other cases may be considered at the discretion of the instructor.

Classroom Rules of Conduct:

A. Cellular Phones, Beepers, Other Communications Devices

While in class, the class should be your primary focus. Disruption of class due to communications devices has become so prevalent that they are a major distraction in class (to you, to the instructor and to other students). For this reason such devices must not be brought to class or must be inactivated/silenced during class.

B. Student Alcohol or Drug Use

Because the classroom is a professional environment students who are suspected of being under the influence of alcohol or drugs will be removed from class. This also meets our legal obligation to provide a drug- and alcohol-free workplace. Such instances will be reported to the Vice-President for Academic Affairs. Students will not be admitted back into class unless such arrangements are made through the V.P. for Academic Affairs.

C. Student Work, Appointments...Etc.

The student who has signed up for the course has made an obligation to participate in those activities scheduled during regular class times. The student must not make other obligations during this time, or that student alone will be responsible for the consequences. The consequences may include reduced or no credit for that portion of the class and inability to make-up the missed work.

D. Withdrawals

The enrollment status of the student in this course is solely the responsibility of the student. If you wish to change your status in this course, be sure that you file the appropriate paperwork with the registrar before the appropriate deadlines. If you wish to drop, do not just stop coming to class!!! Two weeks of consecutive absences will result in your removal from the class. If you do not file withdrawal papers with the Registrar, you will receive an F in this course.

E. Extra Credit

It is your responsibility to get work done on time in an acceptable form. For this reason, no extra credit will be extended during the course of the semester.

F. Technology Issues

Computers make writing and revising much easier and more productive. Students must recognize though that technology can also cause problems. Printers run out of ink and hard drives crash. Students must be responsible for planning ahead and meeting deadlines in spite of technology. Be sure to save copies of your work to disk, hard drive, and print out paper copies for backup purposes. Papers will be submitted to the drop box in the eCompanion website for this course.

G. Make-Up Examinations

The student will be given the opportunity to make-up one examination during the course of the semester, provided that an adequate excuse is provided to the instructor within 24 hours of the missed examination. The instructor will be the final judge of what constitutes an adequate excuse. The makeup examination will be administered on Friday, December 12 at 8:00 AM and will be a cumulative final.

If you miss two exams, one will be scored as a zero and included in your examination average. Missing three examinations will result in a grade of "F" for the course. Three lecture examinations are scheduled for this semester. Your examination average will be calculated from all four test scores. If you feel that one test score is not representative of your effort, you may opt to take the make-up examination.  Failure to sit for the final examination will result in a grade of "F" for the course.

Athletes involved in sports contests or students participating in other school-sponsored events will be allowed to take the examination prior to the scheduled date. The instructor must be given one week prior notice of such an event.

Academic Honesty:
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 2008-2009 Undergraduate Catalog Page 87

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. Park University 2008-2009 Undergraduate Catalog Page 87

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.

Park University 2008-2009 Undergraduate Catalog Page 89-90
Attendance at all class meetings is mandatory. Part of the education of college is preparation for professional conduct. Attendance at work or graduate or professional school is mandatory for remaining employed or in school. Get in the habit of being here all of the time now. Education is also a cooperative effort. You are as responsible for furthering the education of your fellow classmates and the instructor as the instructor is for yours.

It is recognized that personal emergencies will arise during the course of the semester. Four absences (for any reason: illness, personal appointments, doctors appointments car problems...etc.) are allowed without penalty. After 4 absences, 5% will be deducted from the students grade for each subsequent absence. Eight absences is considered excessive, and the student missing eight classes will fail the course. Students who miss class will be responsible for the assignments made and material covered in that class period. Students who enter class after roll is taken will be counted tardy. Two tardies count as an absence. Students who are 15 minutes late (by my watch) will be counted absent.

Exceptions: Athletes who miss class for an athletic contest or students who miss class due to other school sponsored events will not be penalized IF AND ONLY IF THE INSTRUCTOR IS GIVEN TWO LECTURE MEETINGS PRIOR NOTICE AND WORK IS TURNED IN AND EXAMS TAKEN BEFORE THE CLASS IS MISSED!!!!!!!!!! If you have an illness that requires extended hospitalization, have someone contact me!

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.
