Suppose you find a chi-square of .91 from a table with 677 cases. Assume the information was from a 3X3 table. What is the value of the contingency coefficient?
A) .04
B) .08
C) .45
D) .91

Question

Quizplus · Accepted Answer

The contingency coefficient C is calculated using the formula C = sqrt(χ² / (χ² + N)), where χ² is the chi-square value and N is the total number of cases. Plugging in the values, C = sqrt(0.91 / (0.91 + 677)) ≈ 0.04.
