Binning which variables? I will try to implement a k-means algorithm over this dataset:

Team_Categorical  CreditAmount_Numeric   Retired?_Binary
       A                 15.3                   1
       B                 12                     0
       C                 6.2                    1


In order to apply k-means algorithm I need to transform the categorical variables into numeric. So I will apply binning transformaton over the Team_Categorical field. So I will have this dataset:

A    B   C  CreditAmount_Numeric   Retired?_Binary
1    0   0          15.3                 1
0    1   0          12                   0
0    0   1          6.2                  1


My question is: Should I transform CreditAmount_Numeric to binary too?
To answer your question, you need not transform the numeric to binary variable(you meant binning right?).

I will try to explain it with the above example: 


Let's start with row-1 where A = 1 , B =0 , C=0 so it means that you are talking about A. So the value of CreditAmount_Numeric belongs to A and the retired binary value also belongs to A. Similarly, you can deduce for the rest records.

Conclusion is that you need not do any transformation on your numeric variable.
