What does a range check in data entry verify?

A range check in data entry specifically verifies that the data falls within a certain range or boundary. This is crucial for ensuring data accuracy and validity, especially in numerical data entry scenarios. For example, if a field accepts ages, a range check would ensure that the entered age is within a realistic range, such as 0 to 120 years. If a user attempts to enter an age of -5 or 150, the range check would flag this as invalid.

This verification process helps to prevent errors and enhances the quality of data by ensuring that only reasonable and expected values are accepted. By applying such checks, organizations can minimize the risk of processing incorrect data which could lead to faulty analyses and decision-making.
