This question already has an answer here:
I'm pretty new to statistics and I need your help. I just installed the R software and I have no idea how to work with it. I have a small sample looking as follows:
Group A : 10, 12, 14, 19, 20, 23, 34, 41, 12, 13 Group B : 8, 12, 14, 15, 15, 16, 21, 36, 14, 19
I want to apply t-test but before that I would like to apply Shapiro test to know whether my sample comes from a population which has a normal distribution. I know there is a function shapiro.test() but how can I give my numbers as an input to this function?
Can I simply enter shapiro.test(10,12,14,19,20,23,34,41,12,13, 8,12, 14,15,15,16,21,36,14,19)?
