Tukey–Kramer procedure

an extension of Tukey’s honestly significant difference test (HSD test) so that it can be used with samples of unequal size. Whereas the HSD test yields a single critical difference (CD) for each pair of means, the Tukey–Kramer test uses a different CD as required to evaluate the significance of the difference between each pair of means. [John Wilder Tukey (1915–2000) and Clyde Y. Kramer, U.S. statisticians]

compensatory mechanism

a cognitive process that is used to offset a cognitive weakness. For example, someone who is weaker in spatial abilities than in verbal abilities might use compensatory mechanisms to attempt to solve spatial problems, such as mentally rotating a geometric figure by using verbal processes. The underlying theory is that intelligence partly consists of finding ways to compensate for the skills that one has lost over time or in which one was not adept in the first place.
