Final answer:
Care should be taken when adding data to a named range because it can cause errors in formulas if the range doesn't expand, and it may not update in existing charts, potentially leading to data inaccuracies.
Step-by-step explanation:
When working with named ranges in spreadsheet applications, it is important to be cautious when adding data to the bottom of them. If you choose Option 1, it suggests that adding data can potentially cause errors in formulas. This is true because if the named range does not automatically expand to include the new data, any formulas referencing the named range may not account for the additional data, leading to incorrect results or errors.
Option 2 indicates that the named range may not update in existing charts. This is also a legitimate concern because if the chart is referencing a fixed named range, adding new data outside that fixed range will not be included in the chart unless the named range is manually updated to include the new data points.
Why Careful Updates Matter
Therefore, it is essential to ensure that when you add new data to a named range, the range is updated accordingly across all references, whether in formulas or charts, to maintain data accuracy and integrity. Using dynamic named ranges can help mitigate these issues as they automatically adjust to include new data.
