Go onto PsychInfo (or some other database) and find a study that uses archival data. Give me a very brief (two to three sentence) synopsis of the study. What did they look at, and what did they find? Make sure you look at an actual peer-reviewed study (and not just an article that tells you what archival research studies are!)

PLEASE GIVE ME A DIFFERENT ANSWER THAN THE ONE GIVEN BEFORE (I mean, this questions was already answered, but I need a different answer than the one already given.) if the question is unclear, please tell me how it is unclear.
