• Classification model:
  • Make a decision tree for the following:
    • Pick a product that some in your group bought and others didn't.
    • Label the top of the tree with the product description and the next level (first internal node) with the primary reasons you believe there was a difference in purchase (i.e., healthy choice/not healthy choice). Then a final leaf node of 'Yes' or 'No' to the purchase.
    • Add the total number of entries on each node.
• Text model:
  • Perform counts of each of the products purchased and create a Term Frequency graph with the counts being the 'Y' axis and products as the 'X' axis (highest to lowest)
