Which of the following is a guideline for formatting and conventions in spreadsheets?

Using a consistent alignment for data and removing units from numbers in spreadsheets is crucial for clarity and readability. Consistent alignment helps users quickly identify the nature of the data, making it easier to comprehend and analyze. For example, aligning numeric data to the right allows for easier comparison of values, while text should typically be aligned to the left.

Removing units from numbers keeps the worksheet focused on the quantitative aspects, particularly when the units are consistently understood from the context. If every cell in a column represents the same measurement (e.g., all dollar amounts, all percentages, etc.), specifying units in each individual cell can create clutter and distract from the data itself. Therefore, this approach supports better communication of the data's intent and purpose.

In summary, adhering to formatting guidelines such as aligning data consistently and strategically managing unit presentation enhances both the usability and professionalism of spreadsheets.
