Question

10 what advantage is there to having \blind\ subjects in an experiment?
there is no experimenter bias because they do not know which groups the subjects belong to.
the experimenter will not know the role of each of the members of the experiment.
the subjects know what groups they are in, so they can behave the way the experimenter predicts.
there is no subject bias because they do not know which group they belong to.

Explanation:

Blinding subjects means they are unaware of their experimental group (e.g., treatment vs. control). This prevents them from altering their behavior based on expectations, eliminating subject bias. The other options are incorrect: experimenter bias is addressed by blinding the experimenter, not the subjects; the experimenter knowing roles is unrelated to subject blinding; and subjects knowing their group would introduce bias, not prevent it.

Answer:

D. There is no subject bias because they do not know which group they belong to
