   1. AVerdadeiro
   2. BFalso
2. 2Antecedents & Consequents should be marked at the beginning of any ASSOCIATION analysis

   1. AVerdadeiro
   2. BFalso
3. 3Main pillars of association analysis are Frequency of itemsets and Reliability of rules found

   1. AVerdadeiro
   2. BFalso
4. 4Antecedent support is its relative frequency, also called Prior Confidence

   1. AVerdadeiro
   2. BFalso
5. 5“Lift” measures the ratio of rule’s confidence to the overall support of antecedents

   1. AVerdadeiro
   2. BFalso
6. 6Using confidence ratio as rule selection criterion can help to find interesting rules with low prior confidence

   1. AVerdadeiro
   2. BFalso
7. 7Using confidence ratio as rule selection can help us to find lots of trivial rules for very common consequents

   1. AVerdadeiro
   2. BFalso
8. 8Rule support is always lower or equal than Support

   1. AVerdadeiro
   2. BFalso
9. 9For a market basket analysis, tabular data normally requires specifying a customer field and dummy product variables

   1. AVerdadeiro
   2. BFalso

15. 15Buyers of root_vegetables have bought approx. 2.25 more other vegetables than the average buyers of other vegetables

    

    1. AVerdadeiro
    2. BFalso
16. 16Less than 25% of customers bought “other vegetables”

    

    1. AVerdadeiro
    2. BFalso
17. 1710.9% of customers bought “other vegetables”

    

    1. AVerdadeiro
    2. BFalso
18. 18If we set Confidence Difference lower bound to 60, we would not get rules from root_vegetables
