I have three different samples and I would like to check if the means for them differ from each other statistically. I know it is not true if I run 3 different t-test between pairs. I searched and saw ANOVA test can help. But in this case I don't have any response variable (dependent) to run the ANOVA. I have just three independent variables. (3 lists of continuous variables).

It would be really appreciated if anyone can help me. Thanks

The response variable is the measurement i.e. your data.

The predictor (independent variable) is the group/sample/list to which each observation belongs.

Then you would do your ANOVA with this response variable and predictor.

  • $\begingroup$ So, in this situation my predictor variables are categorical (1, 2, and 3). Right? $\endgroup$

  • $\begingroup$ Exactly! Depending on your software implementation, you might have to use a command like as.factor to clarify that $1<2$ doesn't apply and are just arbitrary labels of the groups. $\endgroup$
