Rankings are a way to organize and compare items, people, or groups based on specific criteria. They can be used in various fields, such as sports, education, and business, to show performance, quality, or popularity. For example, college rankings assess universities based on factors like academic reputation and graduation rates. These lists help individuals make informed decisions, such as choosing a school or a team to support. Rankings can change over time as new data becomes available, reflecting improvements or declines in performance. They are often published annually or periodically to keep the information current and relevant.
