Detailed explanation-1: -In a single-blind experiment, participants do not know which group they have been placed in until after the experiment has finished. Example: Single-blind vaccine study You have developed a new flu vaccine.
Detailed explanation-2: -(SING-gul-blind STUH-dee) A type of clinical trial in which only the researcher doing the study knows which treatment or intervention the participant is receiving until the trial is over.
Detailed explanation-3: -Example: Yogurt Tasting The researchers know which yogurt containers are low-fat and which are high-fat, but participants are not told. This is an example of a single-blind study because the researchers know which participants are in the low-and high-fat groups but the participants do not know.
Detailed explanation-4: -A single-blind study is when participants do not know whether they were assigned to the control group or the treatment group. The experimenter, however does know. In a double-blind study, neither the experimenter nor the participants know to which group each participant was assigned.
Detailed explanation-5: -In a single-blind study, patients do not know which study group they are in (for example whether they are taking the experimental drug or a placebo). In a double-blind study, neither the patients nor the researchers/doctors know which study group the patients are in.
