A "Double-Blind" study is a research method used to eliminate bias in experiments. In this setup, neither the participants nor the researchers know who is receiving the treatment or the placebo. This helps ensure that the results are not influenced by expectations or preconceived notions. This approach is commonly used in clinical trials for new medications, where it is crucial to assess the effectiveness of a drug without bias. By keeping both parties unaware, researchers can obtain more reliable data, leading to better conclusions about the treatment's impact on conditions like disease or health issues.
