Both Double-blind experiment and Double-control experiment refer to an experiment where neither the participants nor the administrators know which group is receiving the treatment.
The correct answer is Double-blind experiment. In a double-blind experiment, neither the participants nor the administrators know which group is receiving the treatment. This is done to prevent biases or expectations from influencing the results.
The correct answer is "Double-blind experiment". In a double-blind experiment, neither the participants nor the administrators are aware of which group is receiving the treatment. This is done to minimize biases and ensure that the results of the experiment are objective. To arrive at this answer, you can eliminate the options that are not relevant. In this case, the options "Secret-blind experiment," "Hidden experiment," and "Double-control experiment" do not accurately describe the scenario where both the participants and administrators are unaware of the treatment groups. Therefore, the correct option is "Double-blind experiment."
