Basically, i have 4 tests and 1 control.

For example.

Test1 Test2 Test3 Test4

20       25      15        10       
30       45      10         15
..         ..         ..          .. 
..         ..         ..          ..
15       23       13        45 

The inference is at alpha=0.05. they are all independent. I am trying to find if they differ or the same.

Do i use the following method.

Step 1. I create matrix using data.frame. for example test1<-c(20,30..etc)

Step2. is this correct? or do i use aov().. anova(lm(dependent~independent*independent, data=name) this is what i am confuse.

I think i did something wrong. I need to find the correct F statistic test.

any help.
