<DIV>Mark,</DIV>
<DIV>I disagree.</DIV>
<DIV> </DIV>
<DIV>I think the most likely answer is D</DIV>
<DIV> </DIV>
<DIV>A, B & C are all testing</DIV>
<DIV> </DIV>
<DIV>Validation occurs at the Input (Data entry) stage to limit the entry of inaccurate data eg using Data Validation feature of Excel or using field formatting in a database. So based on our students experience of doing the Spreadsheet and Database outcomes I think most would choose D.</DIV>
<DIV> </DIV>
<DIV>From the Potts textbook </DIV>
<DIV>"Validation is the process by which data that has been input to a computer is assessed to ensure <STRONG>that it is correct and</STRONG> complete. </DIV>
<DIV>...</DIV>
<DIV>Electronic validation relies on software functions to perform <STRONG>checks on accuracy</STRONG>, completeness and reasonableness." (p.12, highlighting added)</DIV>

It cannot be D because validation does NOT check the <BR>ACCURACY of data, only its reasonableness.
