[R-sig-teaching] prop.test in R

[Laura Chihara]

Hi,

I have a question about prop.test in R:

I teach students the score confidence
interval for proportions (also called
Wilson or Wilson score interval).

prop.test(,..., correct=FALSE) gives this
interval.

The default uses a continuity correction.
When should we use one over the other?
Is it worth going over this in class? Why
is correct=TRUE the default?

Thanks for any pedagogical guidance here!
