Q

Twenty sprint cyclists were randomly selected to be in a study designed to test the effectiveness of 12 weeks of creatine supplementation on performance. Ten cyclists received a creatine supplement for 3 months while the other ten received a powdered supplement with the same color and texture that has no physical effect for 3 months. The cyclists did not know which pill they were taking but the researcher did. This study is an example of:
