2. You are expected to show facility with regression analysis procedures and vocabulary, to use terminology correctly, and to correctly and concisely carry out the assignment steps.
3. It is expected that your assignments will be presented in good academic form, including tables formatted in approximate APA style rather than being simply pasted in from SPSS printout, statistical tests summarized in narrative text containing the information necessary, and appropriate analyses and comments included, not just a dump of the results of a test.
