How can totals and subtotals be added to a worksheet?

Adding totals and subtotals to a worksheet is effectively done by summarizing group data within the column. This method allows for the aggregation of data points, which can be either a total for all data in that column or subtotals for specific groups within that column. This approach is fundamental in data analysis as it enables users to derive insights from grouped information easily, aiding in understanding larger datasets and making informed decisions based on that summarized data.

By summarizing group data, the worksheet becomes more informative and manageable, allowing users to focus on key metrics without losing sight of the individual contributions to those metrics. This method ensures clarity and promotes better analysis by presenting data in an organized manner. The correct option highlights the functionality within many spreadsheet tools, where functions such as SUM, AVERAGE, or creating PivotTables can effectively generate these summaries.

Other options do not provide the necessary method for adding these summaries. Editing column properties may adjust formatting but does not calculate totals. Advanced calculations imply complexity that isn't required for simple totals or subtotals. Rearranging column display impacts how data is visually organized, but does not influence the calculation of totals or subtotals itself.
