For the same bivariate table,Cramer's V is .27 and lambda is zero.What can we conclude?
A)A computational mistake has been made.V can never be greater than lambdA.
B)This is a negative relationship.
C)There is no association;disregard V.
D)The variables may be associated even if lambda is zero.Disregard lambda if the row marginals are very unequal.

In this case, we can conclude that the variables may be associated even if lambda is zero. Lambda measures the strength of association between two variables based on the difference in the proportion of cases in which both variables are present, compared to the proportion of cases in which only the row variable is present. A lambda of zero indicates no association based on this measure. However, Cramer's V takes into account the size of the contingency table and can detect association even when lambda is zero. Therefore, we should disregard lambda if the row marginals are very unequal and rely on Cramer's V instead.
