   Question

   A psychologist was interested in whether the amount of news people watch (minutes per day) predicts how depressed they are (from 0 = not depressed to 7 = very depressed). What does the interpretation of the constant?

   

   
   
   1. FALSE: The average depression when the variable news equals its mean
   2. FALSE: The average depression is 7.241 when news exposure increases by 1 unit.
   3. FALSE: As news exposure increases by 1 minute, depression increases by 7.241 units.
   4. TRUE: The average depression is 7.241 when news exposure is zero
   
   

   Solution

   This is the definition of the interpretation of the constant. The constant represents the average value of the dependent variable Y when all the independent variables equal zero.
