A supermarket chain in Pune finds that customers who buy bread and butter very often also buy jam, and uses this to arrange shelves. Which data mining technique has it applied?

The chain has applied association rule mining, also called market basket analysis. It identifies items that are frequently purchased together, such as bread, butter and jam, so that shelf layouts can be planned. The other techniques detect outliers, forecast over time, or classify records, which is not the goal here.

  2. BAnomaly detection

Explanation

Discovering items frequently bought together is market basket analysis, which uses association rules. Anomaly detection finds unusual records, time series forecasting projects values over time, and decision trees classify records into predefined classes.
