I. Course Information
     A.  Catalog description:  The logic of hypothesis testing and assumptions underlying its use are the framework for studying analysis of variance and covariance and multiple regression. These tools are learned in the context of application to psychological research. Students learn to complete statistical analyses using a microcomputer statistical package and to interpret the results.

     B.  Course description: This course will provide a detailed description of fundamental research methods with their associated statistical procedures.

II. Objectives of course:

  The purpose of this course is to help you understand how statistics, as scientific tools, help researchers answer scientific questions. Please do not be overly concerned if you do not remember very much from your previous statistics course(s). This is actually quite typical. Because students arrive at graduate school with various degrees of exposure (and confidence) with statistics, we will be starting at the beginning. This course will be much like an advanced version of an introductory undergraduate statistics course, covering the same topics – descriptive statistics, hypothesis testing, t-tests, chi-square, correlation, and analysis of variance among them - but in somewhat greater depth.

  One central purpose of this course is to prepare students to interpret data from real research. You, as students, will frequently provide the data for us to analyze in class. Research indicates that individuals process information more deeply when it is personally meaningful to them. Research also shows that nothing is more personally meaningful to people than themselves ;) so you will act as participants on a few occasions.

  We will primarily tackle statistics at a conceptual level. We will utilize both hand-calculations and computer analyses (SPSS) for most of the computations in this course, but you will be in a stronger position to excel on the exams if you understand what various statistical techniques do and what they mean. I do not require students to memorize formulas in the class, but the exams will necessitate a sophisticated knowledge of the purpose and appropriate application of various statistical techniques.

III. Learning Objectives:  Students will:

  develop greater understanding of the various statistical techniques utilized in psychological research

  increase their competency for selecting appropriate statistical techniques (when, for example, an independent-samples t-test is used)

  learn how to conduct these statistical techniques through the use of a computer-software package (SPSS)

  increase their critical thinking about scientific research

  Students will enhance their ability to write APA-style results sections

IV.  Class format: Assigned material will be discussed and clarified. Class time will also be used to discuss SPSS applications.

Policy on Academic Integrity (Plagiarism): see more detail at Plagiarism (Tulane)

"Plagiarism is the intentional or unintentional presentation of another person's idea or product as one's own. Plagiarism includes, but is not limited to the following: copying verbatim all or part of another's written work; using phrases, charts, figures, illustrations, or mathematical or scientific solutions without citing the source; paraphrasing ideas, conclusions, or research without citing the source; and using all or part of a literary plot, poem, film, musical score, or other artistic product without attributing the work to its creator. Students can avoid unintentional plagiarism by carefully accepted scholarly practices. Notes taken for papers and research projects should accurately record sources of material to be cited, quoted, paraphrased, or summarized, and papers should acknowledge these sources in footnotes."
