Remember my rant about students not being able to tell which of two
numbers (both between 0 and 1) is larger? Well look at this statement from one
of my students: The mean IQ of freshman at East Carolina Unviresity sic (N
= 17, M = 107.65, SD = 9.95) was significantly less than that
Sounds like your students need to eat more organic food.

Gotta say, I love North Carolina barbecue, but I want it prepared by
people who know whether cook to an internal temperature of at least
145 degrees means less than 145 degrees'll be just jimdandy.

Hello
This is presumably why we have invented standard scores expressed as whole
integers, such as IQ, SAT, T-score and GRE rather than

The S-B current edition has a SD of 15. I guess 15 won.
I stand corrected. To confirm, I've found a history of the SB
on the web which goes through the different versions. The
5th Ed, 2003, version of the SB now has an SD=15.
I think the prediction from Karl's observation is that if the obtained t
is 1.0999783 and the critical t is 1.1113, then many students would
make a mistake in choosing which was larger.

I think Bill is right about the implications of Karl's observation. While I
expressed it here imperfectly, what I do is what Michael suggests. I am
explicit that there are two ways to skin the cat and either gives the

Yes, most high schools have mathematics graduation requirements but...
struggling through high school algebra with a minimum grade is far from
learning all of the material in the curriculum at a level that will make it
likely that it will be retained.

Part of the problem is that Elementary Education is the last haven for college

I remember the Dean of the School of Education (the biggest producer of

Do they have the same problem if you restate it in terms of percentages?
So, if p= 5%, circle which of the following is smaller:
a) 1%
b) 10%
c) 3%
d) 6%
If they can't do this, then your students in are in real trouble.
Then again, if you re-frame it into:
