Answer:

 

An observational study is a study in which the investigator observes the effect of the factors, diagnosis, and treatment and other type interventions.

mixas84 [53]

<u>Based on the information, Dr. Germain's test</u> appears to have proved that high-school seniors' scores on the test and high scores in their freshman gpas one year later are two events that tend to happen together (75 out of every 100 times).

<u>But correlation does not imply causality</u>, so he cannot predict with these results that those who got senior scores in high school will perform as good (and better than others) when they become freshmen.
