Question

Quizplus · Accepted Answer

Gamma and lambda are measures of association between two categorical variables. They are based on the logic of proportional reduction in error, which compares the actual agreement between the two variables with the expected agreement under the assumption of independence. Therefore, the best choice is D, proportional reduction in error. Chi square is a statistical test used to assess independence between two categorical variables. Associational percentaging and proportional repartitioning are not valid concepts in statistical analysis.
