Helen works for a bakery and gathered 600 students for her experiment. Once the students arrived, Helen randomly assigned them to taste a cinnamon bun that was either wrapped in a cheap plastic bag, or placed on a plain paper plate, or boxed in a fancy paper box. After the students tried their sample, Helen asked the students to rate the taste of the cinnamon bun on a scale of 1 (very bad) to 10 (very good). Answer the following five questions: (a) identify the Independent Variable and its levels, (b) identify the Dependent Variable, (c) describe very specifically how Helen should do the "random assignment" for her study, (d) predict what results Helen would obtain based on the notion of perceptual confirmation, and (e) briefly explain why by relating to what belief(s) or expectation(s) is (are) being confirmed.
