Blind study, also known as a single-blind study, is where the participants are unaware of the purpose of the study or what group they belong to. In Gwen's case, she can make the data collectors unaware of which participants are in the control group and which are in the experimental group. This will prevent the data collectors from producing biased observations based on their knowledge of the purpose of the study. Therefore, choice A (blind) is the best answer.
