GCU PSY550 2021 October Discussions Latest (Full)

PSY550 Research Methods

Week 1 Discussion

DQ1 How does the scientific method point towards truth? What is truth, and how do you know when you have found it? Access and read the GCU Statement on Integration of Faith and Work. How might a person with the Christian worldview recognize when they have found truth?

DQ2 Contrast deductive and inductive reasoning, and explain how they can each be used to generate a hypothesis.

Week 2 Discussion

DQ1 Define reliability and validity in your own words. Briefly describe the different types of reliability and validity, including why it is important to conduct a study that is reliable and valid.

DQ2 Stanley Milgram's obedience to authority experiment is one of the most controversial studies in psychology's history. Access and read the GCU Statement on the Integration of Faith and Work. Considering this example, how might a person with a Christian worldview approach these types of experiments from an ethical standpoint?

Week 3 Discussion

DQ1 Discuss the proper placement and usages of a table and a figure within the manuscript.

Define the four general writing guidelines using APA style. Why is it important to write using these guidelines when communicating your study? Explain.

DQ2 Discuss what stage in the publication process should potential authors talk about publication credit. Explain.

Describe how the sections of a poster, for presentation, are organized.

Week 4 Discussion

DQ1 In your own words, define naturalistic observation. Discuss examples of when a naturalistic observational study would be the most appropriate design to select. What are two sources of bias during an observation period?

DQ2 Discuss the advantages and disadvantages of the following nonexperimental research methods: (a) naturalistic observations, (b) surveys, and (c) correlational studies. If you were asked to use one of these designs in a study next week, which nonexperimental design would you select and why?

Week 5 Discussion

DQ1 One of the best-known longitudinal designs is Lewis Terman's study of giftedness. He began tracking gifted children into adolescence and adulthood in 1925; the study is supposed to conclude in 2020. Explain the unique benefits of such a study, and then explain the problems caused by this type of design.

DQ2 Explain the circumstances when a quasi-experimental design would be preferable to a between-subjects design, but also discuss why an explanatory research method is superior to a predictive method.

Week 6 Discussion

DQ1 Contrast the three types of factorial designs.

DQ2 Lay out the design for two between-subjects experiments: (a) an experiment involving an experimental group and a control group, and (b) a factorial design with three independent variables that have 3, 2, and 2 levels, respectively.

Week 7 Discussion

DQ1 Suppose that, for a t-test, your computed value for t is +3.28. The critical value of t is +2.048. Explain what this means. Do you reject the null hypothesis or not? Now suppose that you have 28 degrees of freedom and are using a two-tailed (nondirectional) test. Draw a simple figure to illustrate the relationship between the critical and the computed values of t for this result.

DQ2 Choose an article from the newspaper, an online source, or a magazine, then identify the descriptive statistics included in the article. Were the statisitcs appropriately described in the article? Explain. Discuss if the descriptive statistics used in your source supported the arguments made in it. Were the descriptive statistics misleading? Explain.

Figures and Tables (total of two from paper)

DQ2 A researcher computed the F ratio for a four-group experiment. The computed F is 4.86. The degrees of freedom are 3 for the numerator and 16 for the denominator.

Is the computed value of F significant at p < .05? Explain.

Is it significant at p < .01? Explain.
