SYLLABUS

EXPECTATIONS

Content

This course is designed to acquaint students with the interpretation of basic inferential  statistics as they would be used in social research. The focus will be on the application, computation, and interpretation of these statistics.

Materials


The course consists of reading, lectures, demonstrations, written assignments, and discussion. It is your responsibility to keep current on these materials.

Attendance


Frequent absences will do nothing to increase my confidence that you have learned the material covered in this class. I will take attendance into consideration when determining final grades.

Assignments


There will be numerous homework assignments. These will be graded; it is expected that they be turned in on the day due. I will relent only in cases of extreme hardship such as plague, pestilence, famine, or other university approved excuse.

Honesty


Cases of cheating or plagiarism will result in no credit (0) for the assignment or test and an overall failing grade for the course.

Participation


Frequent participation in class discussions will assure me that your are awake, alert, involved, and are familiar with the material.  
Prerequisites
You must have completed an introductory course in descriptive statistics.

Quizzes


There will be frequent quizzes. The topics and relevant reading are shown in the syllabus. In computing your overall grade I will drop your lowest quiz score.  The quizzes will be based on materials in the study guide, lecture notes, and the assigned readings.

Make Ups

Your first missed quiz will count as your lowest grade and will be dropped. You may make-up any subsequent test, quiz, homework assignment, or paper, but you will loose one point per day for makeups unless you have a University-approved excuse justifying the delay.  

Make-up tests and quizzes will be conducted cheerfully only when:

• You have made prior arrangements with me, and your absence is related to an approved University-related function.  Otherwise I will drop the quiz as your lowest quiz score.

• You have had a death in your immediate family.

• You have had an illness. In this case I will require a note from the physician.

Makeups MUST be completed the week you return to class.

Final Exam

There is an OPTIONAL final exam.. It covers the entire course.  If you get 80% or better on the final I will raise your grade one letter.

Grades

Your grades will be computed as follows:
Quizzes:  70%
Homework: 30%

Grade Scale

Grades will be calculated on the following scale:
A  90% and above
B  80 - 89%
C 70 - 79%
D 60 - 69%
F less than 60% 

Office Hours

Hours I will be available to discuss the course, the weather, or any topic of mutual interest at the hours posted above. If these are not convenient, please see me to make an appointment at another time.
Special Sessions
I will schedule regular special tutoring sessions. I will coordinate them with the class.

Extra Credit 

None

Special Needs

If you have special learning needs, please let me know. Students requiring special considerations should get in touch with the Office of Services for Students with Disabilities. This office will notify me in writing of the accommodations you need in compliance with 504/ADA. If you have special learning needs, please let me know.
