What is two way frequency?

Two-way relative frequency tables show us percentages rather than counts. They are good for seeing if there is an association between two variables.

From the given table, Divide each count by its row total to get the relative frequencies.

For females,

[tex]\frac{18}{54}=33.3[/tex] percent

[tex]\frac{36}{54} =66.6[/tex] percent

For male,

[tex]\frac{28}{84}=33.3[/tex] percent

[tex]\frac{56}{84} =66.6[/tex] percent.

so, [tex]36[/tex] of [tex]54[/tex] females had purchase a condo and [tex]20[/tex] of [tex]30[/tex] males had purchase condo.

Hence, the option A is correct answer.
