Hello,
I am teaching an Introduction to Statistics course in psychology, and in
class the other day, I brought up the issue that SAT scores and IQ scores
may not really be interval scales. My TA pointed out that they are
*standardized* tests, and that the intervals really are designed to mean
something. I came back with the comment that we really don't know what these
tests measure.
Without raising the specter of what IQ and SAT tests really measure, does
anyone have any comments that might be helpful in telling students what to
think about this? Either that, or any references that discuss this issue
explicitly.
Thanks!
Bill
