I have 3 independent variables (Mined area, Reclamation age and reclaimed forest area) and 1 observed variable (conductivity). I ran multiple regression analysis with spss but I am not sure how to interpret the results.

• I have standard error 236.175 is it too high?
• On coefficient section RF(reclaimed forest) and AvgRecAge(reclamation age) is not significant Can I still include them in the model? Thanks!

Here is link for data
