Card 86 / 104: Three years ago an inpatient chemical dependency center in a hospital asked their clients if they would like to undergo an archaic form of therapy created by Wilhem Reich known as “vegotherapy.” Approximately half of the clients stated they would like try the treatment while the other 50% stated that they would stick with the tried-and-true program of the center. Outcome data on their drinking was compiled at the end of seven weeks. Today—three years later—a statistician compared the two groups based on their drinking behavior at the end of the seven weeks using a t test. This study could best be described as
A) correlation research.
B) a true experiment
C) a cohort study.
D) causal comparative research.
