The χ² statistic (also known as the chi-squared statistic) is commonly used as a significance test for examining tables of counts. It measures the difference between the observed counts in the table and the expected counts, under the assumption that there is no association between the variables. The higher the chi-squared value, the less likely it is that the observed counts are due to chance alone, and the more evidence there is for an association between the variables.
