Respuesta :

neither the experimenter nor the people in the experiment know what the experiment is about

Answer:

In a double-blind experiment neither the experimenter nor the people in the experiment know what the experiment is about.

Explanation:

A double-blind experiment is when both parts lack information about the experiment, or the information that they have does not influence the results. Past experiences in the life of both experimenter and people on the experiment, can bias the results. To reduce or eliminate biases in the results, double-blind experiments are developed. Therefore, the people that designed the experiment do not administrate it.
