John,

3 thanks: Thanks for checking gaussEP out on gnumeric. I'm pleased to

hear that it works. Thanks for your tips. I set this up 15 years ago

in MathCad and never implemented it in the classroom because I set my

sights too high--with all the histogram plots started, I wanted them to

grow before the user's eyes with the values being used for one

calculation of the function, and the resulting value of the function,

"lighting up" while the calculation was taking place. Your web document

http://www.av8n.com/physics/uncertainty.htm

motivated me to set it up again, this time on a spreadsheet. Thanks for

making such a well-written, well thought-out document available.

I used gaussEP in lab for the first time yesterday. Beyond error

analysis, it turns out that using it results in an immediately practical

reason for finding an algebraic solution to a problem (rather than

working with numbers from the start). Figuring out what to type into

cell A2 of the first worksheet is a lot easier when one has, on paper, a

correct algebraic expression for the function. One can easily see the

one-to-one correspondence between what one has written and what one

needs to type into A2, which, instead of =sqrt(2g(h-h')) was typically

=sqrt(2*g!a2*(h!a2-hp!a2)).

I read about your "crank three times" method in your uncertainty

document but I appreciate the reiteration. I think I'll probably

implement that in lab later this semester to help convey the idea of

what the spreadsheet is doing.
