Concept explainers
When the chi-square test value is significant and there is a relationship between the variables, the strength of this relationship can be measured by using the contingency coefficient. The formula for the contingency coefficient is
where χ2 is the test value and n is the sum of frequencies of the cells. The contingency coefficient will always be less than 1. Compute the contingency coefficient for Exercises 8 and 20.
