Because of its ease of computation, it is sometimes known as Tukey's Quick Test. This spreadsheet contains intermediate numbers used in calculating the Tukey-Kramer test. This gives rise to the normality assumption of Tukey's test. Each population is called a treatment. This however leads to an obvious question: which particular means are different? Seeking further information after the results of a test is called post‐hoc analysis.

From Tukey's HSD test it was inferred that when Rohtak (3) is opted as a reference category then it has maximum number of stark and significant difference with all 5 districts viz. Tukey a (also known as Tukey’s HSD for honest significant difference). It shows the actual differences between groups and indicates which differences are statistically significant. Tukey’s test calculates a new critical value that can be used to evaluate whether differences between any two pairs of means are significant. In a world awash with data and computers, it is tempting to automate the process of scientific discovery by performing comparisons between many pairs of variables in the hope of finding correlations. The literature on pairwise multiple comparisons (PMC) is reviewed. The Tukey HSD test. Tukey’s HSD test. test is a if-sample generalization of the Wilcoxon test.

This is the simplest way to get a test for Tukey nonadditivity. Both tests are based In a general framework, this approach, called pairwise comparisons, is a specific case of “a posteriori contrast analysis” (see entry on contrast), but it is specific enough to be studied in itself. , flnding a difierence when none exists) equal to the chosen alpha level (e.
