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
C = √X2 / X2 + n
Where X2 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.
