assistant: Ok... How did you allow for random fluctuations in score?
We are all very conscious of the fact that there are
considerable variations in an individual's IOWA score.
Assuming for a second that we're going to assume that the
sample will "average out" the fluctuations, how large are
the various sample groups?
Doesn't this depend upon age, and is this expectation on
LEVEL of learning and not GROWTH?  Also, this may be
impacted upon by other factors; financial, even religious.
Isn't there a hidden financial factor here as well?  Most
minorities live in urban areas and are poor.  Do YOUR
minorities really fit into that group, or are they, in fact,
sufficiently different to skew the results?
These have exhibited problems which place them in a specific
group... Of all the groups listed, this is the one most
likely to be accurately defined...
Again, lower socioeconomic is also associated these days
with urban areas, and this, in turn, is often associated
with other factors such as one-parent homes, violence,
drugs, multi-generational histories of poor education, etc.
I think that one would see differences in a poor rural
community which had access to decent schools, for example,
or where there might be immigrants who embrace literacy
but are poor (asians in the early 1900's perhaps, jews in
the mid 1900's, etc)...
Then I would look to these, and other, variables...
I'm surprised only by the remedial students, but even here
there is an extenuating factor; the nature of the remedial
program itself.  Many remedial programs are inadequate and
fail the students; perhaps yours does not?  This plays into
the discussion I've been having with Chuck (that I'm trying
to drag you into <g>)...
But there ARE "hidden" variables that can make a significant
difference in the outcomes!  One of the biggest may be the
apparently random fluctuations in IOWA scores!
