When the Friedman test leads to significant results, at least one of the samples is different from the other samples. The Friedman Test William Friedman (1891 – 1969) developed statistical methods for determining whether a cipher is monoalphabetic or polyalphabetic and for determining the length of the keyword if the cipher is polyalphabetic. Such experiments also have practical value, argues Friedman, ... says Shalm, whose team at the NIST is exploring whether Bell tests could be used in quantum cryptography. The Friedman test indicated that mobilization altered the activity of the right temporal muscle (p = 0.00010), both masseters (p = 0.0000), right sternocleidomastoid (p = 0.00251), left sternocleidomastoid (p = 0.00033), and right and left digastric muscles (p = 0.00045 and p = 0.00000, respectively).
