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.)
