Rates, often referred to as scores, are numerical values that represent the performance or quality of a specific subject. These scores can be used in various contexts, such as evaluating the effectiveness of a product, the quality of a service, or the performance of an individual. Common examples include credit scores, test scores, and customer satisfaction ratings. Scores are typically calculated based on a set of criteria or benchmarks, allowing for comparisons between different subjects. For instance, a credit score helps lenders assess the risk of lending money, while test scores indicate a student's understanding of the material.
