A preliminary study shows an association between conservative attitudes and a higher likelihood of having a degenerative condition,such as heart disease or high blood pressure.The researcher decides to perform a simple elaboration of the association by running cross-tabulations of the attitudes-degenerative conditions link separately for those who are under the age of 50 and those who are 50 years of age or older.The reason the researcher does this is that
A)degenerative conditions may actually cause people to be more conservative.
B)older people may be more likely to be conservative and to have degenerative conditions.
C)age might be a mediating variable between attitudes and degenerative conditions.
D)it can help to get rid of any bias introduced if the sample is not probabilistic.
