Course Description The purpose of the course is to give you a working knowledge of descriptive statistics and how they are used and interpreted in psychological research. Descriptive statistics deal with the ways in which a collection of numbers can be summarized for clearer understanding and presentation. Descriptive statistics also underlie inferential statistics techniques that allow you to infer properties about populations from data collected on samples from those populations. This course will cover fundamental concepts and techniques of descriptive statistics (e.g., graphical presentations, measures of central tendency and variability, correlations) and their applications to psychological research, as well as introduce the basic underlying logic of inferential statistics, including hypothesis testing with the normal and t-distributions. Format The course format consists of one three-hour class each week. Classes will consist of lecture, research demonstrations/data collection, and, on some occasions, tutorial review. Each class will usually be associated with a chapter in the textbook. Please note that the professor will not lend out or post lecture notes; it is your responsibility to borrow a classmate's notes if you must miss a lecture. You should do the readings before the lecture so that you will have a frame of reference for understanding the material presented. When learning statistics you are dealing with cumulative knowledge: a new topic builds on previous topics. Therefore, it is essential that you attend the lectures and that you do not fall behind in your readings and assignments. Please do not hesitate to ask questions during the lectures or office hours. Method of Evaluation Grades are based on the total number of points accumulated on 1) weekly assignments 2) brief report 3) a midterm, and 4) final examination.
Weekly Assignments: At the end of each lecture you will be given a set of problems. In most cases they will be taken from your text. You are to hand in each assignment at the following lecture; assignments will not be accepted late. Your answers will not be marked for correctness (for some of the questions you will be able to check the answer yourself by looking at the answers provided at the end of the text). Anthony will simply verify whether or not you have completed the assignment. It is not sufficient to merely put down answers; you must also provide the steps that led to the answer. If you hand in all of your work throughout the semester you will receive 5 full marks towards your final grade. The purpose of these marks is to provide you with an incentive for keeping up with your work and to provide you with a reward for your efforts. Brief Report: You will be assigned a small research assignment. A description of this assignment and its due date will follow shortly. Exams: There will be a midterm exam and a final exam (the final exam is cumulative). The midterm is scheduled for February 10, 2004. The final exam will be scheduled during the final examination period. The format for the exams is closed book, but partial formulas and relevant tables will be provided. You will need to bring a calculator for all exams. The final breakdown of marks is as follows: Weekly Assignments: 5% Brief Report: 15% Midterm Exam: 35% Final Exam: 45% Grading scheme for letter grades 0 - 44 F 45 - 49 E 50 - 54 D 55 - 59 D+ 60 - 64 C 65 - 69 C+ 70 - 74 B 75 - 79 B+ 80 - 89 A 90 -100 A+ Drop Date: The last date to drop the course without academic penalty is March 5, 2004.
Guidelines for Missed Tests and Quizzes 1. You must contact me (in-person, by telephone or by E-mail) within 48 hours of the test. If you do not speak to the me directly (i.e., leave a message on my voicemail or with my secretary, Zehra Bandu at 736-5115 ext. 66232), be sure to clearly state your name, student number, course, and a number/time at which you can be reached. If you are unable to contact me during this 48 hour period, subsequent documentation accounting for the delay must be provided. 2. Appropriate documentation verifying the circumstances for the missed test must be provided. Failure to provide appropriate documentation will result in a grade of F on the missed test. A. Tests missed on the grounds of medical circumstances must be supported by an Attending Physician’s Statement or a Statement by a Psychologist or Counsellor. The Attending Physician’s Statement must include (i) the full name, mailing address and telephone number of the Physician, (ii) state the nature of the illness and its duration (i.e., specific dates covered), and (iii) an indication of whether the illness and/or medication prescribed would have SERIOUSLY affected the student’s ability to study and perform over the period in question. Note: The Physician’s office may be contacted to verify that the forms were completed by the Physician. B. Tests missed on the grounds of non-medical circumstances must be supported by appropriate documentation, i.e., death certificates, obituary notice, automobile accident reports, airline/train/bus tickets/receipt for emergency travel (with date of booking on ticket), etc. Airline/train/bus ticket/receipts for emergency travel must indicate destination, departure and return dates. 3. In the case of a missed TEST that is legitimately documented, A MAKE-UP will be PROVIDED. You must be prepared to write within the week following the missed test (a date will be set by the instructor). Although the content to be examined will be the same, the format may or may not follow that of the original test. It is your responsibility to check with me as to the date/time of the make-up. A conflict in another course during the time of the make-up is not an acceptable reason for missing the make-up (unless there is an examination in the other course at that time). If a student misses a make-up opportunity for good reasons (see points A and B above), the missed make-up must be supported by appropriate documentation (see point A and B above).
