Numerical labeling is a method used to assign numbers to items, making it easier to identify and organize them. This technique is commonly applied in various fields, such as inventory management, where products are labeled with unique numbers to track stock levels and sales. In research, numerical labeling can help categorize data points, allowing for efficient analysis and comparison. For example, in scientific studies, researchers may use numerical labels to identify different test subjects or experimental conditions, facilitating clearer communication of results and findings.
