Which report should a store manager review to analyze the trend of her store's scores for the year?

The satisfaction report is the most relevant choice for a store manager looking to analyze the trend of her store's scores over the year. This report typically aggregates customer feedback and performance metrics related to how satisfied customers are with their experience in the store. By reviewing this report, the manager can assess customer perceptions, identify areas for improvement, and track changes in satisfaction levels over time.

Understanding trends in satisfaction scores can provide insights into the effectiveness of any implemented changes or initiatives aimed at enhancing the customer experience. It directly reflects the overall health of customer relationships and can inform future strategy.

The other options, while important in their own contexts, do not provide the specific focus on customer satisfaction scores that the store manager needs. Performance reports may include various operational metrics, sales reports focus on financial performance, and retention reports often deal with customer loyalty rather than their satisfaction levels. Therefore, the satisfaction report is clearly the most aligned with the manager's goal of examining year-long trends in customer satisfaction.
