EMC Proven Professional – Data Science and Big Data Analytics — Question 8

You are using the Apriori algorithm to determine the likelihood that a person who owns a home has a good credit score. You have determined that the confidence for the rules used in the algorithm is > 75%. You calculate lift = 1.011 for the rule, "People with good credit are homeowners". What can you determine from the lift calculation?

Answer options

• A. Support for the association is low
• B. Leverage of the rules is low
• C. The rule is coincidental
• D. The rule is true

Correct answer: C

Explanation

A lift value of 1.011 suggests that the association between homeowners and good credit is very weak and likely coincidental, as it is close to 1. Options A and B do not specifically address the meaning of the lift value, while option D incorrectly implies a strong association exists when the lift indicates otherwise.
