However, if I got those values two things would immediately attract my notice: the first set of values looks suspiciously bimodal. Your sample size is also too small to really check for normality.

There are multiple version of Cohen’s d for Student t-test.

We will provide examples of R code to run the different types of t-test in R, including the: T-test conventional effect sizes, proposed by Cohen, are: 0.2 (small effect), 0.5 (moderate effect) and 0.8 (large effect) (Cohen 1998). The d statistic redefines the difference in means as the number of standard deviations that separates those means. Calculate and report the t-test effect size using Cohen’s d.Add p-values and significance levels to a plot.t.test() : R base function to conduct a t-test.The result is a data frame, which can be easily added to a plot using the ggpubr R package. t_test() : a wrapper around the R base function t.test().Perform a t-test in R using the following functions :.This article describes how to do a t-test in R (or in Rstudio).
