I haven't seen it used as a word in its own right. The two compounds
homoscedastic and heteroscedastic are common enough: the first means
"having equal variances", in relevant subgroups, such as the two populations
in a t-test, or across values of the predictor in regression. The second
means unequal variances. The C is pronounced hard, and sometimes spelt K,
It's Greek, of course, from a word meaning able to be dispersed.
