Hi campers. A little audience participation question. Validation types in the study design are:<br><ul><li>existence checking</li><li>range checking</li><li>type checking</li></ul>The <a href="http:///postmortems/2010sd/SD2010exam.htm#c4">2010 SD exam</a> decided to muddy the waters by describing these validation tests:<br>
<br clear="all"><i>Existence - to make sure that the number entered exists on Medicare's database<br>Null - to make sure something has been entered<br></i><br>Now, I've always read "existence" as "has a value been entered?" (like "Null" in the exam question).<br>
<br>How many of you good folk refer to existence testing as "existence in a limited list", and how many would equate existence testing as null testing?<br><br>If you agree that the exam's terminology is unconventional, I am a bit concerned about it being used in an exam where it could confuse students who were taught the conventional interpretation.<br>
<br>Now I'm even doubtful about what the study design means by "existence checking" - does it mean "null checking"?<br><br>Have a happy winding-down time, if you're luck enough to have one!<br>
