Final answer:
In project management and spreadsheets, grouping data allows you to reorder and summarize information based on selected criteria, facilitating data analysis and understanding.
Step-by-step explanation:
The way to reorder task or resource information in a table and to display summary values according to various criteria that you can choose is called grouping.
