Create a controlled comparison using crosstabulations using the following information.

You hypothesize that Democrats are more supportive of abortion than Republicans but fear the relationship could be spurious because of ideology.

63% Democrats who are conservative support abortion rights
37% Democrats who are Conservative do not support abortion rights
20% Republicans who are conservative support abortion rights
80% Republicans who are conservative do not support abortion rights
82% Democrats who are liberal support abortion rights
18% Democrats who are liberal do not support abortion rights
35% Republicans who are liberal support abortion rights
65% Republicans who are liberal do not support abortion rights

Draw a line graph.

Does this demonstrate an additive, spurious, or interactive relationship?
