An Insightful Alternative for Calculation of the Pearson Chi-Squared Test Statistic

Sponsor: Quality and Productivity Section
Keywords: goodness-of-fit, test for indpendence, contingency table

Duane K. Allen, Lean Six-Sigma Black Belt Consultant

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.
