It often employs a numerical scale, such as 1 to 5 stars, where higher scores indicate better quality or satisfaction. Rating systems are commonly used in various fields, including movies, restaurants, and products, to help consumers make informed decisions. These systems can be based on individual opinions or aggregated data from multiple users. They may also include written reviews that provide additional context. Overall, rating systems aim to simplify choices and enhance transparency in consumer experiences.
