s no conceptual connection between the data values in each sample dataset. Another type of t-test is called a paired sample test, which might be used when you have some sort of before and after data, such as a test score before some instruction followed by a test score after the ...
Paired Sample T-Test Formula The correlated t-test, or paired t-test, is a dependent type of test and is performed when the samples consist ofmatched pairsof similar units, or when there are cases of repeated measures. For example, there may be instances where the same patients are repeate...
