Sample Data Checking Questions

   
 

Data Checking questions consist of items of data that must be checked against each other. This type of test is used to measure how quickly and accurately errors can be detected.

This data may be either meaningless, for example account numbers, or may be fairly meaningful, for example names and addresses. In both cases is vital to check each character rather than ‘read’ the data normally. You should also bear in mind that there may be more than one error in any single piece of data.

These tests usually contain between 20 and 40 questions and take 10-20 minutes to complete. It is important, although difficult, to maintain your concentration for the full duration of the test. The speed at which you can answer these questions is the critical measure, as most people could achieve a very high score given unlimited time in which to answer.
