Rating is a system used to evaluate or assess the quality, performance, or value of a product, service, or experience. It often involves assigning a numerical score, letter grade, or star rating based on specific criteria. Ratings help consumers make informed decisions by providing a quick reference to the overall satisfaction or effectiveness of an item. Ratings can be found in various contexts, such as movies, restaurants, and products. They are typically based on user reviews, expert opinions, or a combination of both. This feedback can guide potential buyers and influence their choices in the marketplace.
