On this page we show you how to: (a) carry out an independent-samples t-test using the t.test function; (b) generate useful descriptive statistics including the group means, standard deviations, sample sizes, and the mean difference.
Description. Performs one and two sample t-tests on vectors of data. Usage. t.test(x, …) # S3 method for default. t.test(x, y = NULL, alternative = c("two.sided", "less", "greater"), mu = 0, paired = FALSE, var.equal = FALSE, conf.level = 0.95, …) # S3 method for formula. t.test(formula, data, subset, na.action, …) Arguments. x.
