<DIV><FONT size=2 face=Arial>Dear Corpora members, I wonder if you could advise
me which math. statistics criteria is more reliable to state the difference
between two samples, that is, t-test or chi-square? I used t-test to see the
difference in the occurrence of all colours in the texts of 26 British and
American writers. Should I also use the chi-square criterion to substantiate the
difference between two samples or t-test is reliable enough? Looking forward to
hearing from you to <A href="mailto:yutamb@mail.ru">yutamb@mail.ru</A>
Remain yours sincerely Yuri Tambovtsev, Novosibirsk,
