About the Course

This course will give you an opportunity to examine the principles of descriptive statistics and the application of these statistical techniques in observational and correlational research. We will focus on the process of developing appropriate strategies for collecting and summarizing quantitative and qualitative data. The course will use a variety of exercises as well as a series of laboratory and field study experiences to develop your working knowledge of statistical concepts and enable you to become a "good consumer" of psychological research. The course will also lay the foundation of knowledge necessary for those of you interested in pursuing careers in psychology or other fields involving quantitative research.

Course Goals

1. Describe distributions using descriptive statistics

2. Collect and analyze descriptive data from observational and survey research

3. Test for statistical significance when assessing the relationship between two variables

4. Discuss the use of probability and theoretical distributions in applying descriptive statistics

5. Apply statistical problem solving skills and logical reasoning to develop effective data analytic strategies

6. Use Excel spreadsheets and SPSS-PC statistical software to analyze quantitative and qualitative data

7. Critically assess the use of descriptive statistics in newspapers, magazines, websites, and a wide variety of other contexts.

Course Requirements

1. Problem Sets: Since practice and feedback are critical for learning, you will be required to complete selected problems sets from the Jaccard & Becker text (see syllabus for problem numbers and due dates). These assignments must be completed on time and will represent 15% of your final course grade. Mastering statistics demands that you constantly build on previously learned concepts so falling behind on your homework can have disastrous consequences. Make sure to attempt all problems assigned and find help if you need it (hint: the TPJ Center is a excellent place to find stats. tutors). You must show your work for your assignment to be considered complete. Answers to selected problems are presented at the end of the text so most of the fun and credit will come from showing the process you used to arrive at the correct answer.

2. Quizzes: Short quizzes based on the assigned homework and text readings will be given periodically to assess your mastery of the material and prepare you for the tests. The format of the quizzes will vary and may include true-false, calculation problems, short essays, multiple choice questions, and graphing.

3. Tests: You will have two tests which will count 15% towards your final grade. The tests are scheduled for 9/24 and 10/31 and will include true-false, multiple choice, calculation problems, graphing, and short essay questions.

4. Comprehensive Final Exam: A cumulative final exam covering concepts from throughout the course will account for 15% of your final course grade.

5. Attendance: Class attendance is mandatory. Absences that are required by sports or medical related reasons will need to have appropriate documentation. Course grades will be lowered for failure to comply with this attendance policy.

6. Lab Reports: Throughout the semester we will conduct a series of laboratory exercises designed to help you develop your observational and survey skills and master APA style. These labs will require you to conduct statistical analyses using the SPSS software and write a brief lab report summarizing the nature of the research question, the methodology used to investigate the question, the results of the investigation, and your conclusions. Together these lab reports will represent 15% of your course grade. Although much of this course deals with quantitative concepts, the lab reports you produce should represent your best writing. Please make sure your reports conform to the general principles of expository writing presented in Chapter 2 of the APA publication manual. As with all writing, the orderly presentation of ideas, the smoothness of expression, and the use of good grammar can facilitate clear communication.

7. Statistical Research Project: To provide you with practice in translating descriptive research and statistical results into written narratives, you will complete a statistical research project in successive stages of drafts and edits. This project will present the findings from the laboratory component of the course using APA style and formatting. Specific guidelines will be provided once we begin our class projects.

Course Policies

  1. All assignments and project components must be submitted on time (on the due date and at the beginning of the regularly scheduled class corresponding to that date). Late work (anything handed in after the due date or after the beginning of class) will be penalized by deducting five percent of total points available on that assignment per day. If work is more than two days overdue, it will not be accepted and a grade of "0" will be issued. The only exceptions to this policy will be for absences approved by the instructor.
  2. Cheating and/or Plagiarism: It is the policy of this course that any cheating and/or plagiarism will subject you to an automatic F for the entire course and a reporting of the incidence to appropriate administrative processes that may result in your dismissal from Rollins.
  3. Diagnosed learning disabilities must be registered with the Academic Resource Center before special consideration can be given in regards to testing mechanics or format.

Discalimers: The following schedule is a publication of my best intentions for the coverage of topics and due dates. Because something almost always gets in the way of best intentions to keep them from being realized, I reserve the right to change any of the topics for coverage, assigned due dates, or any rules or procedures published in this syllabus. Changes will be announced in class.
