Do children prefer purple juice or yellow juice? Two different supplements, which have no effect on taste, are used on identical
juice to produce purple juice or yellow juice. Volunteer children are randomly assigned to either purple juice or yellow juice, and they are asked to rate the juice on a scale from 1 point to 10 points. Is blinding demonstrated in the experiment? No, because the volunteers do not know the color juice they are getting Yes, by having the experimenter in a separate room pick one of the two containers at random and having a juice pulled from that container remotely Yes, by having the statistician analyzing the results not know which volunteer sampled which juice Yes, by having the volunteers wear a blindfold while drinking the juice out of the container, so that they don't know the color juice they are tasting No, because the volunteers know whether they are drinking purple juice or yellow juice
