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.
