WK 7 DQ1 (Elaborated)PSY550-Research MethodsWK 7 DQ1 (Elaborated)PSY550-Research Methodsuppose 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.Choose an article from the news...

WK 1 DQ 2 (Elaborated)PSY550-Research MethodsvWK 1 DQ 2 (Elaborated)PSY550-Research MethodsTopic 1 Discussion 2: Question: Contrast deductive and inductive reasoning and explain how they can each be used to generate a hypothesis.

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

WK 6 DQ 2 (Elaborated)PSY550-Research Methods.WK 6 DQ 2 (Elaborated)PSY550-Research Methods.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. A between-subjects experiment would include a control group and an experimental group.

WK 7 DQ 2 (Elaborated)PSY550-Research MethodsWK 7 DQ 2 (Elaborated)PSY550-Research MethodsTopic 7 DQ 2 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.

WK 8 DQ 2 (Elaborated)PSY550-Research Methods.WK 8 DQ 2 (Elaborated)PSY550-Research Methods.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. 1. Is the computed value of F significant at p < .05? Explain. 2. Is it significant at p < .01? Explain

Instructions: This is an open-book and open-notes exam. You have 2hours to complete the exam. The test is worth 100 points; each item is worth 10 points. 1. Chuck Wagon is very excited about the within-subjects approach. “Now I’ll never need to run large numbers of subjects again,” he says. However, Chuck has forgotten that within-subjects designs may be a) useless, b) impossible, c) confounded by order effects, or d) impractical when excessive subject time spent in an experiment makes ...
