When would you add column totals in a worksheet?

Adding column totals in a worksheet is particularly useful for displaying overall summary data alongside detailed records. This approach allows users to quickly grasp the aggregate information while still having access to the more granular details that can support further analysis. By including totals, you provide context and insight into the overall trends and patterns found within the detailed data.

While options like hiding detailed records or solely showing summarized data suggest decreasing the amount of information presented, they do not serve the purpose of offering a comprehensive view that includes both summary and detailed insights. The idea of eliminating collation of data also goes against the fundamental purpose of analytics, which is to structure and present information effectively for evaluation.
