How do I apply the "decision tree model" to the "friends & family" data set

sky

I can't find the input to connect "friends & family" to. Here's where I'm at:

 

P.S. I'd really appreciate it if you can help me solve #8-12. All files attached.

Hi @sky,

 

To apply the model Decision Tree on your "family data", you need an Apply Model operator.

To feed the mod (model) input of this operator, you can multiply the mod output of the Decision Tree operator using a Multiply operator :

For the last questions, you have to play with the parameters of the Decision Tree operator and see how it affects the results :
