   Question

   When performing a regression analysis, the regression equation is determined by minimizing:

   
   
   1. TRUE: the total squared error (residual) between the predicted and the observed Y values
   2. FALSE: the total absolute error (residual) between the predicted and the observed Y value
   3. FALSE: the total absolute error (residual) between the values of X and Y
   4. FALSE: the total squared error (residual) between the values of X and Y
   
   

   Solution

   The regression equation is meant to plot out the perfect line through all datapoints, meaning the least total squared error (residual) between the predicted and the observed Y values
