Comparative analysis is a method used to evaluate two or more items by examining their similarities and differences. This technique is often applied in various fields, such as business, education, and social sciences, to make informed decisions or draw conclusions. By systematically comparing attributes, researchers can identify patterns and trends that may not be evident when looking at each item in isolation. In practice, comparative analysis involves collecting data on the subjects being compared, which could include products, policies, or theories. Analysts then assess this information to highlight key distinctions and advantages, helping stakeholders understand the implications of their choices and guiding future actions.
