Do hamsters preferred treats or blue treats? Two different supplements, which have no effect on taste, are used on identical treats to produce a red treat or a
blue treat. Volunteer hamsters are randomly assigned to either a red treat or a blue treat, and the researchers rate the treats based on how quickly the hamsters
eat them. Is blinding demonstrated in the experiment?
No, because the hamsters do not know the color treat they are getting
Yes, by having the experimenter in a separate room pick one of the two containers at random and having a treat pulled from that container remotely
No, because the hamsters know whether they are eating a red treat or a blue treat
Yes, by having the statistician analyzing the results not know which hamster sampled which treat
Yes, by having the hamsters eat the treats out of the container, so they don't know the color of the treat they are eating
