• Review Chapter 5 from the APA manual, “Displaying Results.”

• Review the media resources demonstrating the multiple regression..

The assignment:

Hi. Could you please attach the example in the text outlined on pp. 490–493

Complete Smart Alex’s Task #4 on p. 355 to perform a multiple regression analysis using the Supermodel.sav dataset from the Field text. You can follow the steps outlined on pp. 316–320 as a guide.
