Cluster Analysis
Cluster Analysis is a way to organize data into meaningful groups that helps businesses understand their customers better. Think of it like sorting a closet - you group similar clothes together to make them easier to find. In market research, professionals use this method to group customers with similar shopping habits, preferences, or behaviors together. This helps companies create better marketing strategies and product offerings. You might also hear it called "market segmentation" or "customer grouping" when reading job descriptions. It's a key skill in market research that helps companies make smarter business decisions.
