Multiple regression in practice

To be an quantitative article 

Write a 3- to 5-paragraphs critique of the article (2 to 3 pages). In your critique, include responses to the following:

• Why did the authors use multiple regression?
• Do you think it’s the most appropriate choice? Why or why not?
• Did the authors display the data?
• Do the results stand alone? Why or why not?
• Did the authors report effect size? If yes, is this meaningful?
