    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:

    Subject: [Corpora-List] Statistical tests for corpus studies

    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
