- Discuss the four assumptions of ANOVA.It would not be ethical to assign one group of children to smoke in order to study the effect. so, in lieu of this type of direct experimentation other forms of evidence are commonly accepted. Describe two of the common types of evidence that can be used to establish a cause-effect relationship when direct experimentation is not possible.In ANOVA, main effect always refers to?
- What source of variation is found in an ANOVA summary table for a within subjects design that is not in an ANOVA summary table for a between subjects design. What happens to this source of variation in a between-subjects design?What is the relative risk for the association between men and women vs COVID-19 infection? What do you conclude?A researcher conducted a research that majority of people who died during pandemic bought a new phone during last year. What type of research is this? If his assumption is correct which statistical test should be appropriate to analyze the data?
