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:

    To the old saying that man built the house but woman made of it a “home” might be added the modern supplement that woman accepted cooking as a chore but man has made of it a recreation.
    —Emily Post (1873–1960)

    ... the big courageous acts of life are those one never hears of and only suspects from having been through like experience. It takes real courage to do battle in the unspectacular task. We always listen for the applause of our co-workers. He is courageous who plods on, unlettered and unknown.... In the last analysis it is this courage, developing between man and his limitations, that brings success.
    Alice Foote MacDougall (1867–1945)
