In a single-blind study, who is "blind" to the treatment?

A) the peer-reviewers
B) the participants
C) the experimenters
D) both the experimenters and participants

Answer: B
Rationale: In a single-blind study, only the participants are prevented from knowing the true purpose of the study and which type of treatment they are receiving (for example, a placebo or a drug). In contrast, in a double-blind study, both the participants and the experimenters are "blind" to the exact treatment each participant receives until after the study has concluded.
