This article shows how to conduct a t-test in R/Rstudio using two different ways: the R base function t.test() and the t_test() function in the rstatix package. We also describe how to interpret and report the t-test results.

- How To Do Two-Sample T-test in R
You can run a t test in R using the t.test () function in base R. This has options you can use to analyze one sample t tests, paired t tests, and two sample t tests. Before I explain how you can conduct a t test using R, I will first explain why exactly it is needed and how it works.
14 mar 2023 · In this tutorial, we will learn about the classification of t-tests (one-sample, two-samples, and paired sample t-test) with R code examples and learn to interpret the results. Note : if you are new to R, take a mini Introduction to R Programming course to understand the basics.
27 sie 2024 · In this post, we will learn how top perform t test in R and understand when and why to use it. A t-test is one of the commonly used statistical tests, when one is interested in comparing two groups of measures and determine if there is a significant difference between the mean values of two groups.
22 sie 2022 · T tests are statistical tests used to compare the mean of two samples. The null hypothesis is usually that the mean (or average) is the same in both groups. Once you' ...more. If you are doing...
The t-test is used to compare two means. This chapter describes the different types of t-test, including: one-sample t-tests, independent samples t-tests: Student’s t-test and Welch’s t-test; paired samples t-test. You will learn how to: Compute the different t-tests in R. The pipe-friendly function t_test() [rstatix package] will be used.
Solution. Sample data. Comparing two groups: independent two-sample t-test. Paired-sample t-test. Comparing a group against an expected population mean: one-sample t-test. Problem.
