Detailed explanation-1: -A Paired T-Distribution and Paired T-test (Paired T Distribution, Paired T-Test, Paired Comparison Test, Paired Sample Test) are statistical methods that compare the mean and standard deviation of two matched groups to determine if there is a significant difference between the two groups.
Detailed explanation-2: -Paired comparison tests are used to indicate which of two samples has more of an attribute being tested, or to indicate which of two samples is preferred. In the latter application, it is considered to be an acceptance test. It is one of the most used attribute difference tests, and is easy for panelists to understand.
Detailed explanation-3: -Paired comparison tests can be classified as simple difference tests or directional paired comparison tests (or 2-alternative forced-choice (2-AFC) tests); usually, they are implemented with two samples, but they are also possible with multiple samples (multiple paired comparison test).
Detailed explanation-4: -For effective sensory evaluation, the analyst should duly recognize the purpose of the study, select the appropriate experimental design, use panelists who fit the purpose, choose the proper method for preparing and presenting the samples, and analyze the data cor-rectly.
