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 6 DQ1 (Elaborated)PSY550-Research MethodsWK 6 DQ1 (Elaborated)PSY550-Research MethodsContrast the three types of factorial designs. Definitions A factorial design is a research design in which participants are analyzed, observed, and monitored across the combination of levels with two or more factors. The three types of factorial designs are between subjects’ design, mixed factorial design, and within-subject design (Privitera, 2019)
