That's a good point. Even when we know the total sampling frame and contact them all, we rarely see more than a 10% response rate. We often go on the assumption that whoever responded was a random selection (occasionally checked via phone interview) and if so, the overall estimates of ATTITUDES will be accurate. However, wanting to know how many could have responded is a different problem. Hm. Nets are sounding better all the time! ;-) > >In reponse to the question from Bob Muenchen as to "How did you >get the R-help figure?"

The figures from UGA cover SAS (3,253) and SPSS (2,105). I'm still waiting to hear from people about Statalist and S-NEWS. I'll post them on the site as soon as I have those. Thanks!
