Friedman Test - Post Hoc Analysis

Post Hoc Analysis

Post-hoc tests were proposed by Schaich and Hamerle (1984) as well as Conover (1971, 1980) in order to decide which groups are significantly different from each other, based upon the mean rank differences of the groups. These procedures are detailed in Bortz, Lienert and Boehnke (2000, pp. 275).

Not all statistical packages support Post-hoc analysis for Friedman's test. But user contributed code exists that provides these facilities (for example in SPSS, and in R )

Famous quotes containing the words post and/or analysis:

    Fear death?—to feel the fog in my throat,
    The mist in my face,
    When the snows begin, and the blasts denote
    I am nearing the place,
    The power of the night, the press of the storm,
    The post of the foe;
    Where he stands, the Arch Fear in a visible form,
    Yet the strong man must go:
    Robert Browning (1812–1889)

    Cubism had been an analysis of the object and an attempt to put it before us in its totality; both as analysis and as synthesis, it was a criticism of appearance. Surrealism transmuted the object, and suddenly a canvas became an apparition: a new figuration, a real transfiguration.
    Octavio Paz (b. 1914)
