Review Questions

• How does cluster analysis aid in the segmentation process for businesses?
  • Cluster analysis aids in the segmentation process by grouping customers with similar behaviors or characteristics into distinct clusters. This allows businesses to better understand their target audience, leading to more effective marketing strategies. By identifying these segments, companies can tailor their products and services to meet specific customer needs and preferences.
• In what ways can the results of cluster analysis impact targeting strategies for marketers?
  • The results of cluster analysis can significantly impact targeting strategies by revealing which customer segments are most likely to respond positively to specific marketing campaigns.
