**Notebook**:35,25,40,30

**Smartphone**:20,21,25,30,25

**Watch**:35,20,30,45,35

I want to make a hypothesis like this:

**"Is buyer's age will significanly affect product choices?"**

So the questions:

1. I confuse how to choose independent variable. Is Product choices will be dependent variable?

Can ANOVA calculate where dependent variable is categorical?

2. Is the hypothesis will be Same with:

**"From 3 product choices, are there significanly buyer's age?"**

Thank you for your attention. Sorry for my english
