Some methods of solving the biasedness in Chiâ€“square Contingency table statistic were considered. Phi Coefficient, Contingency Coefficient and Cramerâ€™s V tools were employed to solve the biasedness in the use of Chiâ€“square test. Our results show that any of Phi coefficient, Contingency coefficient or Cramerâ€™s V can be used to describe the association between two variables if the data matrix is 2 x 2. Contingency Coefficient was recommended as a good statistic when the matrix dimension is the same while the Cramerâ€™s V is most adequate when the data matrix differs.
