Paper details:
The experiment was done by our professor having us take an online quiz for a gauge of our general psych knowledge. We took another assesment a week later. Some of the class got detailed feedback, and the other part of the class did not receive any feedback after the first assesment.
For your Project 1 write up you should complete a 3-5 page paper in APA style describing our in class experiment. In addition to the 3-5 pages you should have a title page, any graphs and references. You should include a brief abstract. (Although this comes first in your paper it should be written last.) In your introduction you should describe what was the rationale behind the experiment and provide some supporting research. (Find at least three references) In your methods section, describe the participants, the design, the materials used. Results should include relevant descriptive statistics as well as the results of the paired T test or ANOVA. Your discussion should explain the results and put them into a broader context.
