Abstract:
|
Pearson's classical formula for the chi-squared test statistic is applicable to the observed (o) and expected (e) frequencies of categorical data. This poster presentation develops a general Pearson's chi-squared test statistic formula by introducing a parameter q. Proper selection of q can improve the contrast of the values of the formula's summation terms, which leads to improved visual exploration of the categorical data.
