margin of error

[Dennis Roberts]

I worked on a small handout for my stat class about the margin of error (like the +/- 3% used in polls) . While I fully acknowledge that I got the idea from Moore and McCabe's book "The Practice of Statistics", I put it in the context of examples used in my own classes.

I think this notion ... is far too often OVERlooked ... and could be very beneficial to the planning of some kinds of studies.

The link above ... scroll down to marerr1.doc ... and RIGHT click to SAVE TARGET AS (or you can double click and see what happens) ... it's a small Word document.

Comments appreciated.
