Dear Josephine,
I would recommend the log-likelihood statistic over chi-squared as it is applicable to a wider range of frequencies. For more details see:

Dear all,
As a lay-man to statistics, I wish to get some advice on the tests suitable
for comparing the frequency of a specific type of word in corpora of
different genre. Having in mind are Chi-square and ANOVA but I'm not sure
they are the appropriate ones.
Thanks in advance
