Course Description:  This class is the first in a sequence of two methodology courses for students intending to major in psychology. It provides an introduction to basic statistical concepts, methods, and applications.  The aim of the course is to encourage the development of practical skills in the analysis and interpretation of real psychological data, and to help students become educated consumers of the research literature in psychology and related fields. To that end, our focus will tend to be conceptual rather than mathematical, applied rather than theoretical (e.g., it will be more important to understand why a particular statistical technique is appropriate, and how to make sense of the results obtained from its use, than to understand the full mathematical underpinnings of the statistic).  During the course we will make frequent use of the computer to analyze data, although you will also be asked to carry out hand computations illustrating key statistical principles. You don't need to be an accomplished mathematician to do well in this course.  The ability to reason in a logical manner is more important to successful understanding of psychological statistics than the ability to manipulate complex equations. The course does involve numbers -- there's no escaping that -- but if you have basic arithmetic and algebra skills, the mathematical component of the course will be straightforward.

 

Course Prerequisites:  Mathematics 111 or equivalent.

 

Required Textbooks:

Aron, A. & Aron E.N. (2002). Statistics for the Behavioral and Social Sciences: A Brief Course (2nd. Ed). Upper Saddle River, NJ: Prentice Hall.

Renner, C. (2002). Study Guide and Computer Workbook. Upper Saddle River, NJ: Prentice Hall.

 

Lectures and Laboratories:  Attached is a list of lecture topics and reading assignments.  Please read the relevant section of the text before the lecture to which it corresponds. Note also that lecture notes will be available on the Blackboard web site (see below) prior to each class.  To avoid copying down class overheads, please bring these notes to class.  In addition to attending lectures, you must also enroll in and attend one of the 3 weekly statistical laboratories run by the class TAs: Mon 2-3:20 (George); Tues 8:30-9:50 (Jonathan); Tues 12-1:20 (Jonathan).  The labs will be held in 180 Straub, the Psychology Department’s computer lab (open 8am-9pm Monday through Thursday, and 8-5 Friday).  The labs will provide an opportunity to gain hands-on computing experience relevant to concepts discussed in lectures. The statistical software for this course is SPSS for Windows Version 11.5.  It is installed on the computers in 180 Straub.  The labs will also involve discussion of the weekly problem sets, as well as allowing you the chance to raise any questions you have concerning lectures or the textbook. Labs begin in Week 1 with an introduction to the SPSS computer package.

 

Exams:  There will be two midterms and a final exam. Make-up exams will only be given in extreme circumstances (e.g., serious illness or injury) and there will be no early exams.  All exams will be cumulative, with an emphasis on more recent material.  Exams will be closed book. Questions will mostly be conceptual but some will involve calculation.  However, since comprehension rather than memorization is the goal, we will provide a list of mathematical formulas; your job will be to know what formula is relevant to a particular problem and how to use it correctly.  It will be helpful to have a calculator for the exams but to receive credit for calculation problems you will need to show each step of your calculations; do not rely on advanced calculators that directly compute complex formulas. 

 

Problem Sets:  To understand is to do:  Just like practicing piano or tennis, you need to exercise your statistical muscles.  To help you with this, take home problem sets will be assigned each week.  Assignments will normally be due in class on the Monday after they are handed out.  Late problem sets will not be graded unless prior arrangements have been made. The problem sets will be graded on a 10 point scale (0-10). Collaborative learning is encouraged: If you want to discuss the problems with other students, feel free to do so. However, the answers you turn in should be written independently.  If you have difficulties with the problems, please consult with the TAs or with me.

 

Grading:  The problem sets will count for 30% of your grade, the midterms for 20% each, and the final for 30%.

Blackboard: The course web site can be accessed through the Blackboard course information system. On the web site, you will find general announcements for the class, lecture notes, problem sets and solutions, links to relevant web sites, and more. You will need an account on the Blackboard system; students enrolled in the course will receive email before the first week of the term with their account name and initial password. To visit the course site, go to http://blackboard.uoregon.edu, login, and then select "Statistical Meth Psych" from the list of blackboard course sites in which you are enrolled. If you need help logging in or using Blackboard, see http://blackboard.uoregon.edu/local/usingbb/. Also you can get help by going to the library Information Technology Center (ITC) and/or see http://libweb.uoregon.edu/kitc/faq/blackboard.html#help.
