Review Questions

• How does leverage enhance the effectiveness of decision-making in business analytics?
  • Leverage enhances decision-making by allowing businesses to utilize data relationships to derive actionable insights. By understanding how different items or behaviors are connected within datasets, companies can make more informed choices about marketing strategies, inventory management, and customer engagement. This leads to improved efficiency and effectiveness as organizations can act on data-driven findings rather than relying solely on intuition.
• Discuss the relationship between leverage, support, and confidence in association rule mining.
  • In association rule mining, leverage, support, and confidence are interconnected metrics that help evaluate the strength and usefulness of discovered rules. Support indicates how frequently an itemset appears in the dataset, while confidence measures the likelihood of one item appearing given another. Leverage then assesses how much more likely the items are to co-occur compared to what would be expected if they were independent. Together, these metrics help determine which associations are statistically significant and worth acting upon.
• Evaluate the implications of high leverage values in terms of strategic business decisions.
  • High leverage values suggest a strong relationship between itemsets in a dataset, indicating that these items are more likely to be associated than random chance would allow. This insight can significantly impact strategic business decisions by directing resources towards products or services that show promise based on customer behavior patterns. By focusing on high-leverage relationships, businesses can optimize marketing efforts, tailor promotions effectively, and improve overall operational efficiency.
