   Question

   The table below is from the article by Dekovic et al. (2008), Factors associated with traumatic symptoms and internalizing problems among adolescents who experienced a traumatic event.

   

   The variable physical proximity has three response options: low, medium and high. Looking at the table above, what might be a legitimate criticism of the way the analysis was conducted and/or reported?

   
   
   1. FALSE: The researchers would have been better off centering the variable physical proximity first before including it in the analysis.
   2. FALSE: The researchers would have been better off including the variable physical proximity first, and only then demographic control variables.
   3. TRUE: The researchers would have been better off including dummies in the analysis for the variable physical proximity.
   4. FALSE: There really should have been an asterisk after the beta of physical proximity (.01).
   
   

   Solution

   Physical proximity is a categorical variable. To include categorical variables in a regression analysis, dummies of them must be created.
