I have done some ANOVA tables for some data that I have, from this I can read the within-group variance. can anyone tell me how i may find out the between-group variance?

Hi Emma,>>R gives you the tools to work this out. ## Example set.seed(7) TDat <- data.frame(response = c(rnorm(100, 5, 2), rnorm(100, 20, 2))) TDat$group <- gl(2, 100, labels=c("A","B")) with(TDat, boxplot(split(response, group))) summary(aov(response ~ group, data=TDat)) Regards, Mark. emj83 wrote:> > can anyone advise me please? > > > emj83 wrote: >> >> I have done some ANOVA tables for some data that I have, from this I can >> read the within-group variance. can anyone tell me how i may find out the >> between-group variance? >> >> Thanks Emma >> > >-- View this message in context: http://www.nabble.com/Between-group-variance-from-ANOVA-tp24954045p25121532.html Sent from the R help mailing list archive at Nabble.com.
