t-Tests in R (1-sample, paired samples, & independent samples)

In this video, I demonstrate how to run the following tests in R:
1. The 1-sample t-Test
2. The Paired Samples t-Test
3. The Independent Samples t-Test
In this video, I assume that you already understand the concept and logic of a t-test. My only goal is to show you how to run the analysis in R.
This is a longer version for people who want to go in-depth. There is also a shorter version where I just focus on how to run the analyses with a few lines of code: • t Tests in R (SHORT VE...
NOTE: In the independent samples t-test example, I show you how to pool the variances. Because the 2 sample sizes are equal in that example, we could also have just averaged the variances. But the procedure I showed you will work even if your sample sizes differ.
WARNING: When coding in R, I ignore most coding conventions. What you see me do may not be the "proper" or traditional way to do things in R.
