Hello everyone here. We have a question that says a double blind experiment is a double blind experiment is when neither the patients nor the researchers know which study group is the control group or an experiment group. So our choices are a an experiment where the control and experimental groups cannot be recognized by technicians or participants. This is true. Be an experiment where the participants in an experiment know about the control and experimental groups. No they do not know. See an experiment where only the technicians collecting data know about the control experimental groups know the technicians do not know in a double blind D. An experiment where every person involved knows about the control and experimental groups. No no one should know about the control and experimental groups. So our answer here is a an experiment where the control and experimental groups cannot be recognized by technicians nor participants. Thank you for watching. Bye.
