Have you ever asked yourselves why investment firms advertise in golf magazines and sellers of music in magazines for female populations that are 50+ year old? This has to do a lot with market basket analysis and association rules analysis. Affluent people tend to play golf and grandmothers make up a significant segment of the population that purchases music fro their grandkids. Market basket analyses are behind the decisions to sell, say shampoo in a store, together with a coupon for detergent, for example, or other similar decisions that may not make 'sense' or are readily obvious at a first glance. Can you share other examples that help businesses extend the message about their products or services based on market basket analysis? Please describe the scenarios and provided a brief explanation.
