Quizplus · Accepted Answer

Scheffé is a contrast-based multiple comparison technique that allows for comparisons among all possible pairs of means. It is a conservative approach that controls for Type I error rates, making it the best choice for situations where the number of comparisons is small and a stringent control for error rates is desired. The other options (Dunnett, Student-Newman-Keuls, and Tukey) are not contrast-based techniques and have different levels of stringency in controlling error rates.
