Catalog description: Experimental and other quantitative methods used in the study of behavior. Applied statistical analysis, laboratory experiences, and research writing. Prerequisite: PSY 309 Statistics.

General objectives:

  1. To understand and apply standard methods of empirical research to questions in the field of psychology.
  2. To comprehend strategic and tactical decisions in research, and evaluate them for utility and ethical responsibility.

Learning outcomes: If you successfully complete this course, you should be able to

  1. Understand published research and analyze it to identify the methods used
  2. Critically evaluate research, considering the strengths and weaknesses of the methodology
  3. Design and condict studies that use available methodolgies in an appropriate fashion
  4. Statistically analyze research data and draw data-based conclusions
  5. Write a research report in APA format.

Shared folder: A shared folder has been added to your e-mail account. It should show up in the left panel of your screen as a folder labeled Experimental02 under Public Folders. I intend to use the shared folder to distribute class project and reading assignments, as well as other newsworthy items. I encourage you to use the shared folder to continue class discussions or to raise questions not covered in class.

To find the shared folder for the class, open Outlook. Then, go to the folder list on the left side of your screen. (If it is missing, click the File menu and select Folder list. Scroll to the bottom of the folder list to find Public Folders, and click the plus sign. Click the plus signs beside each of the following, in order: All Public Folders...Academic...Classes...Young P. Click on Experimental02, and you are into the folder. Please read the first message from me, and reply. To read any message in the folder, double-click it. To reply, click the Post Reply button; type your message; and click the Post button. To post a new message rather than a reply, click on the folder. Then click New on the Outlook toolbar at the top of the page, type your message, and click Post. Helpful hint: Click on Experimental02 and drag it up the folder list to Favorites, to eliminate most of the above searching steps in the future. But don't drag it anywhere else. Remember that items you post to the discussion group may be read by any member of the class, including the teacher. However, nobody outside the class has access to your contributions.
