A rating system is a method used to evaluate and score items, services, or experiences based on specific criteria. For example, a restaurant might be rated on its food quality, service, and ambiance. These ratings help consumers make informed decisions, as they can quickly see how others have experienced a particular place or product. In many cases, ratings are presented as stars, numbers, or letters. For instance, a movie might receive a 5-star rating, indicating it is highly recommended. This system simplifies choices for people, allowing them to find the best options based on collective feedback from others.
