Which type of data validation edits are successful in the identification of transposition and transcription errors?
Range check
Validity check
Duplicate check
Check digit
A check digit is a numeric value that is calculated mathematically and is appended to data to ensure that the original data have not been altered, e.g., an incorrect, but valid, value substituted for the original. This control is effective in detecting transposition and transcription errors. A range check is checking data that matches a predetermined range of values. A validity check is programmed checking of the data validity in accordance with predetermined criteria. In a duplicate check, new or fresh transactions are matched to those previously entered to ensure that they are not already in the system.
