Hi,
I am very new to R. I am trying to perform an Anova Test and see if it
differs or not.
Basically, i have 4 tests and 1 control.
Tester
Test1 Test2 Test3 Test4 Control
20 25 15 10 17
The inference is at alpha=0.05. they are all independent. I am trying to
find if they differ or the same.
> test1<-c(20)
> test2<-c(25)
> test3<-c(15)
> test4<-c(17)
> test4<-c(10)
> control<-c(17)
> tester<-data.frame(test1,test2,test3,test4,control)
> tester
test1 test2 test3 test4 control
1 20 25 15 10 17
> anova(lm(tester))
Analysis of Variance Table
Response: test1
Df Sum Sq Mean Sq F value Pr(>F)
Residuals 0 0
I think i did something wrong. I need to find the correct F statistic test.
any help.
thanks.
