<div>Dear Shirin</div>
<div>please note that your qualitative descriptors can be
ordered:</div>
<div>&nbsp;minimally partially sufficiently fully</div>
<div>attributing numerals to those ordered categories</div>
<div>1234</div>
<div>maintains the order but says nothing about the intervals between
those ordered categories</div>
<div>that (estimating intervals) is the task of the investigator using
the Rasch model.</div>
<div><br></div>
<div>Of course it is much easier to NAME some ordered categories than
it is to define them sufficiently to categorize all responses
unambiguously</div>
<div>but that is our aim</div>
<div><br></div>
<div>hope that starts you on the right track</div>
<div>regards</div>
<div>Trevor</div>
