View Full Version : SEM, meaning of... (Statisticians, help!)

So, the SEM (Standard Error of Measurement) more-or-less means that, with all other things being equal, one's score could vary by the value of the SEM on any given session and must be considered essentially the same.

By definition, then, and as long as the score is within the SEM, any score within the SEM is the same as any other score within the SEM.

So, if a passing score is (hypothetically) 175, and the SEM is 3, then a passing score should also be anything from 172-178. No?

Thus, at the bottom end "Pass" is somewhat flexible.

Or am I missing something, here? :confused:
