a.) What sort of research design is used in this study? How do you know? b.) What values go in the last column? Write the (very simple) formula used to calculate the last column below and then go up to the table and fill it out. (Don’t forget to title/label the column.) c.)Conduct the appropriate hypothesis test to determine whether there is a significant difference in participant reports of discomfort in the no VR condition versus the VR condition. Use α = .05. (**SS = 122.95, but still show how you calculated this.)
- Your research team reads the article that is summarized in Question 2. Your team argues that the research design is flawed and that all participants should have been exposed to both conditions in order to observe a true difference. Your team carries out a similar study, yielding the data below.
