Dear All: good morning
*Re:* How to rum Multiple ANOVA and Multiple T-test between the same groups. Your help will be highly appreciated. *1.* is there a way to run multiple t-tests on different variables between the same two groups. *Data for t-tests:* The data frame “dataTtest” has 5 variables (x1,x2,x3,x4,x5) and one factor (factor1) with 2 levels (group1, group2). x1<-rnorm(20,1,1) x2<-rnorm(20,2,1) x3<-rnorm(20,3,1) x4<-rnorm(20,4,1) x5<-rnorm(20,5,1) factor1<-rep(c("group1", "group2"), each = 10) dataTtest<-data.frame(x1,x2,x3,x4,x5,factor1) dataTtest *2.* is there a way to run *multiple ANOVA* and multiple comparisons *Tukey tests* on different variables between the same groups. *Data for ANOVA tests:* The data frame “dataANOVA” has 6 variables (x1,x2,x3,x4,x5,x6) and one factor (factor2) with 5 levels (group1, group2, group3, group4, group5). x1<-rnorm(40,1,1) x2<-rnorm(40,2,1) x3<-rnorm(40,3,1) x4<-rnorm(40,4,1) x5<-rnorm(40,5,1) x6<-rnorm(40,6,1) factor2<-rep(c("group1", "group2", "group3", "group4", "group5"), each = 8) dataANOVA<-data.frame(x1,x2,x3,x4,x5,x6,factor2) dataANOVA with many thanks abou ______________________ *AbouEl-Makarim Aboueissa, PhD* *Professor, Statistics and Data Science* *Graduate Coordinator* *Department of Mathematics and Statistics* *University of Southern Maine* [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
