Which of the following data validation edits is effective in detecting transposition and transcription
errors?

A.
Range check

B.
Check digit

C.
Validity check

D.
Duplicate check

Explanation:

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, newor fresh transactions are matched to those previously entered to ensure that they are
not already in the system.
