We address the question of how to perform a paired t-test in situations where we do not know how to pair the data. Specifically, we discuss approaches for bounding the test statistic of the paired t-test in a way that allows us to recover the results of this test in some cases. We ...

Paired T Test Hypotheses Null hypothesis:The mean difference between pairs equals zero in the population (µD= 0). Alternative hypothesis:The mean difference between pairs does not equal zero in the population (µD≠ 0). Reject the null when the p-value is less than or equal to your ...
You will learn how to: Perform the independent t-test in R using the following functions : t_test() [rstatix package]: the result is a data frame for easy plotting using the ggpubr package. t.test() [stats package]: R base function. Interpret and report the tw...
