especially true when you're comparing really big counts with really small
counts, which is I think what Adam's rule of thumb is meant to address.
Once you've decided that applying the chi-square test even makes sense, then
questions like significance levels and Bonferroni corrections come into play.
Rob Malouf <BR>Department of Linguistics and Asian / Middle Eastern Languages
San Diego State University<BR>I wonder if all the linguists on the Corpora list
are so advanced in math. statistics. Being a simple linguist I did not
understand anithing. I mean why it is not possible to use Chi-square criterion
when the samples are different in size. On the contrary, I read in the books on
Chi-square that it is also possible to use it when the samples are not equal.
However, I want to be on the safe side, so I take the equal samples when
comparing two transcribed texts. I usually take a sample of 10000 speech sounds
from longer texts. I take the sentences from the long texts at random. When the
sample is 10000 I stop. Is it not possible to use the Chi-square in this way? I
am sure the discussion of how to use and how not to use the Chi-square criterion
and other math. statistics criteria in linguistics is very important. Looking
forward to hearing for your advice to <A
