Grouping is a method used to organize items or information into categories based on shared characteristics. This technique helps simplify complex data, making it easier to analyze and understand. For example, in a classroom, students might be grouped by their reading levels to tailor instruction to their needs. In data analysis, grouping can involve clustering similar data points together to identify patterns or trends. This is often used in fields like statistics and machine learning, where algorithms can categorize large datasets, allowing researchers to draw meaningful conclusions from the information.
