A conditional relative frequency table is generated by column from a set of data. The conditional relative frequencies of the two categorical variables are then compared.

An association cannot be determined between the categorical variables because the relative frequencies are not similar in value.

There is likely an association between the categorical variables because the relative frequencies are not similar in value.

An association cannot be determined between the categorical variables because the sum of the relative frequencies is 1.0.

There is likely an association between the categorical variables because the sum of the relative frequencies is 1.0.
