While you can calculate the values on your own and simply add them to the plot under the ggsignif function geom_signif command. The four major ways of comparing means from data that is assumed to be normally distributed are: If you have non-normal data (or if you dont know what distribution your data comes from), you cant use any of the above tests for comparison of means. Questions labeled as solved may be solved or may not be solved depending on the type of question and the date posted for some posts may be scheduled to be deleted periodically.

Connect and share knowledge within a single location that is structured and easy to search. As a reminder, the t-statistic for comparison of two independent groups is computed as: t = X1 X2 S2 1 n1 + S2 2 n2 t = X 1 X 2 S 1 2 n 1 + S 2 2 n 2 where X1 X 1 and X2 X 2 are the means of the two groups, S2 1 S 1 2 and S2 2 S 2 2 are the variances for each of the groups, and n1 n 1 and n2 n 2 are the sizes of the two groups.

Hypothesis testing for the difference of two means. The stat_compare_means function in R is actually a specified function based on the more general compare_means tool that compares all means in a specified string, with the stat extension more specifically telling the program to take calculated p-values and significance data and assign it to the axis in ggplot graphs.
