Do we have to apply feture scaling before spliting train and test set ANS : After spliting into train and test set
Feature Scaling
should we go for standarization or Normilization Standarization mostly works every time, so go with standarization
if the values are one hot enceded then don't do it, becase it will lose its intpretion becase this countries are change
when called feture scalling on train set use same scalar to standarization values of the test set
