Final Exam PS 306, Fall 20021. Suppose that you completed a senior thesis in which you worked out the basic idea of the study in conjunctionwith your faculty advisor, you collected all the data, then worked with your advisor on analyses, and then wentthrough several cycles of revision of your thesis based on feedback from your advisor. Ultimately, two years afteryou graduate, your advisor is interested in including your thesis along with three other studies in a paper to besubmitted to a journal for publication. Using the three principles espoused by Fine & Kurdek, what kind ofacknowledgement do you think would be appropriate for your contribution. [10 pts]Your answer should make explicit use of the principles espoused in the article.2. Dr. Ray N. Deere was interested in the impact of three types of Drug (A, B, and C) on minimizing the negativeimpact of the common cold. A group of 15 people suffering from colds were given one of the three drugs for 3 daysafter first reporting cold symptoms and then asked to rate how comfortable they felt on a 7-point scale (1 = awful, 7= excellent). Complete the analysis seen below, then tell Dr. Deere what he should do next.

Err.Drug ADrug BDrug CMeans Table for Comfort ScoreEffect: DrugFirst of all, you should note the absence of an appropriate control group (no drug/placebo).Then, you should determine how you might increase the power of the study. Including thecontrol group would help enhance the treatment effect, but you might also consider givinga greater dosage of the drugs. You could also work to decrease the error term. Oneapproach might be to use only males or only females. You might also use only people withvery severe colds (through some operational definition, using maximum temperature, etc.).Finally, you can always boost the power by increasing the sample size from 5 to a muchlarger n.3a. Intrigued by the notion that “blondes have more fun,” Dr. Harry Feller (himself a blonde)decided to collect data from people with various hair colors. Because he thought that blondeswould have more fun under a wider range of settings, he decided to collect data in two differentsettings (Work and Home) for 40 people with four different hair colors: blonde, brunet, red, andblack. The dependent variable was a 9-point rating scale of the amount of fun the person washaving “at that time.” Complete the analysis below and interpret the results as completely as youcan. Do the data indicate that you should stock up on blonde hair coloring?

However, at workpeople with red hair had more fun than people with black or brunet hair. At work, peoplewith blonde hair had more fun than people with brunet hair. But, absent a truemanipulation, dying one's hair red (or blonde) would not necessarily lead to more fun atwork (and certainly not at home).3b. Suppose that Dr. Feller decided to ignore the two different settings and analyze his data (from 3a) as a single-factor ANOVA with hair color as the only factor.

Suppose that you were interested in conducting an experiment as a 5x5 design, with a minimum of 30 scores percell.

Briefly describe at least 3 studies that illustrate the operation of experimenter expectancy effects. [10 pts]Clear articulation of the studies illustrating experimenter expectancy effects is essentialhere.6. Using either the West, Gunn, & Chernicky (1975) study from your text (participating in a burglary) or one of thetwo studies used in the class in which we broke into mini-IRB groups, use the APA ethical guidelines to determinewhether or not you would have voted to approve the study. Briefly describe the study before making your argument.[10 pts]As always, your use of the guidelines is more important than the decision you reach. Themore explicit the use of the guidelines, the better the answer.7. Do you ever reach the end of an exam and think, “Damn! He didn’t ask anything about X and I was ready to nailthat question!” Well, here’s your chance. Ask yourself any question that was not asked (or related to) any of theother questions on this exam. Then answer that question. Your grade will be based on both the quality of thequestion and the answer. [5 pts]You need to ask a good question and provide a good
