Final answer:
Marketers collect market research data for products in the introduction stage and competitive analysis for products in the maturity stage.
Step-by-step explanation:
Product Introduction Stage
One type of information a marketer would collect for a product in the introduction stage of the life cycle is market research data. This includes information about target customers, their needs, preferences, and buying habits. By collecting this data, marketers can gain insights to develop effective marketing strategies and tailor the product to meet customer demands.
Product Maturity Stage
On the other hand, for a product in the maturity stage, a different type of information a marketer would need is competitive analysis. This involves examining the offerings of competitors, their pricing, promotions, distribution channels, and customer satisfaction. By analyzing the competition, marketers can identify areas of improvement, differentiate their product, and stay competitive in the market.
