For Data Reduction, we should do the Data Reduction on whole dataset or on the 
dataset after attributes selection we did in classification. Thanks.

On the whole data set would be more reasonable. You can treat the data reduction task 
as an independent one from the previous classification task.

So, if I choose PCA, I just do it on the numeric attributes in my dataset, right? Because 
PCA only works on numeric attributes.

Yes. You may treat binary attributes as numeric ones as well. It is up to you... You need to 
explain in the report.
