3) Doctor Strange wants to research the benefits of exercise on stress. Provide two examples of how he would conduct his study using an experiment, non-experiment, field research, or available data approach. Each example must be a different approach. Again, you must provide two examples

.4) Provide an example of a curvilinear relationship (you cannot use the music or energy drink example).

5) Provide an example of a negative relationship.

6a) Stark Industry wants to test their new drug on third grade students. Before they can start testing, what needs to be done? What IRB category would this be?

6b) What consent form(s) would Stark Industry need? (see previous question)

7) Name two benefits of conducting an interview rather than sending out an electronic survey.

8) Provide a detailed example of a reversal design (ABA). How can you improve it?

9) Thanos wants to conduct focus groups on campus climate at Titan University. There will be four research assistants that will moderate the focus group sessions. What are two ways we can avoid experimenter bias?

10) How can history be a threat to internal validity? Provide an example (you cannot use the lung cancer/smoking example from class).

11) Dr. Adam Warlock is studying the relationship between race and drug incarcerations. His hypothesis is that Black or African American males are incarcerated at a higher rate than non-Hispanic White males. What would be the type I error? Please explain using the example.

12) Dr. Carol Danvers is studying the relationship between race and drug incarcerations. Her hypothesis is that Black or African American males are incarcerated at a higher rate than non-Hispanic White males. What would be the type II error? Please explain using the example.

13) Dr. Proxima Midnight is studying the effects of wine on pregnant women during different trimesters and hypothesizes that wine reduces stress during pregnancy. She performs a posttest-only experiment. She recruits 20 women for her study and randomly assigns them to the experimental group or the control group. The experimental group was given eight ounces of wine every week. The control group was not allowed to have any wine at all. At the end of her study, Dr. Proxima Midnight rejected the null hypothesis. What would be a conceptual replication of this study? Provide a detailed example just like the one mentioned.

14) Should we recruit college students as research participants? Why or why not? Select a side and provide two rationales.

15a) Dr. Cheng is studying the effects of fast food on long distance running. He first obtains a full list of individuals who have participated in the Disneyland Half Marathon in the past five years. He randomly selects a male and female from each state (United States). What sampling method is this?

15b) How many participants are in Dr. Cheng’s study? (see previous question)

16a) Following question 15: After selecting his participants, Dr. Cheng looks at the following variables and their impact on completion time: gender (male/female), type of fast food options (McDonalds, In-and-Out, Burger King, Del Taco, Taco Bell, and none at all), and age (18-24, 25-30, 31-40, 41-50, 51-64, and 65 and older). How many conditions are there?16b) What is the dependent variable? (see previous question)

17) Are open-ended questions a good way to obtain answers from participants? Why or why not? Select a side and provide two rationales.

18) What is a participant variable? Provide a definition and an example.

19) Name two ways of how you can improve reliability. Do not name two types of reliability, but two ways you can improve it.

20) Nova Corps recruits were given a short course in speed reading. The participants were broken up into three groups. Each group had a different delivery method (face-to-face, hybrid, or online). At the conclusion of the 15 week course, participants were asked to read a paragraph and then take a t est of comprehension. Before taking the t est, some participants in each group were provided a monetary incentive ( $10, $100, or none at all). At the end of the t est, the researcher collected the reading Tim e and number of errors on the comprehension t est for each participant. What is/are the dependent variable(s)?

21a) Dr. Quill is studying the impacts of listening to music while studying (hip-hop, rap, country, r&b, pop, jazz, and none at all). The participants were classified as over-achievers, under-achievers, or average. Each group was given a study sheet in which they studied for an hour under each of the music conditions. At the end, they received an e xam that was based on the study sheet. The research assistants calculated the average number of errors per type of music. What variable are we manipulating?

21b) Is this a repeated design? If so, what condition is repeated? (see previous question)22) What is a pilot study and name one benefit of conducting one?23) What kind of t est would you use if you only had one ordinal variable with four groups? Does the type of t est differ depending on whether or not it is a repeated measures design? If so, provide the different types of tests.24) Provide two reasons for debriefing.25) Correlation coefficients describe the ____________________ and ____________________ of a relationship.
