"Scedastic" would mean "to do with spread" and is not in wide
use AFAIK.
"Homoscedastic" and "heteroscedastic" mean "with the same spread" and
"with differing spreads".
According to Robert Pirsig's book "Lila" (sequel to "Zen and the Art")
this is one of a huge family of words all coming from the same
Indo-European root "sk.." including "science", "scatter", "discern",
"shed" (noun and verb), "escape", "schizophrenia", "schism", "scissors",
"shave", "scatological" (and its obvious cognate in coarser English [or
German]), all going back (often indirectly) to the idea of separating
one thing from another.
