which is a good question. But I would ask the prior question:
What, precisely, does Doug want to mean by "normalize"? And is that
meaning congruent with Dennis's understanding of the word?
(THEN I would ask Dennis's question!)
(I note in passing that Doug is in a department of physical science,
and in physical sciences "normal" often has the meaning "perpendicular
to a (line or) plane"; while Dennis is in a department of educational
psychology, where "normal" nearly always refer to the probability
distribution that in physics is often called "Gaussian". I can't tell
from the rather spare context whether any such misunderstanding or
miscommunication applies to the conversation, but if it does, 'twere
better sorted out sooner than later.)
