In Excel, to calculate the top 10% of salespersons, which feature would Isaiah use?

Using conditional formatting in Excel is a powerful way to visualize the top 10% of salespersons. This feature allows users to apply specific formatting to cells based on certain criteria, such as highlighting the top-performing entries in a list.

When Isaiah wants to identify the top 10% of salespersons, he can set up conditional formatting rules that will automatically highlight these individuals based on their sales figures. This visual representation makes it easier to quickly identify high performers without needing to manually sift through data or create additional calculations.

In this context, the other options do not serve the same purpose. Data validation is used for ensuring that the data entered into a cell meets certain criteria, cell protection is about restricting editing access to certain cells, and formula auditing is focused on checking the integrity of formulas within the spreadsheet. These features do not provide the same visual insights or immediate identification of top performers as conditional formatting does.
