Question

true or false: the circle invalid data function will place an oval around invalid data, even if the data was entered before the data validation function was used.

Explanation:

The Circle Invalid Data function in data validation (e.g., in Excel) only marks data as invalid based on the rules set when Data Validation is applied. Data entered before applying Data Validation and not violating the new rules won't be circled. So the statement is false.

Answer:

False
