The researchers decided to perform univariate analyses of each independent variable and each of the three outcome variables. Which independent variables were significantly associated with the risk of a cesarean delivery?

Here’s an example of how multiple regression can be useful in a research study. Sometimes it helps you understand the concept when you see it applied in a real-life scenario. In a study completed by Tussey et al. (2015), laboring women who had received an epidural were randomized into two groups and compared. One group was given routine care; the experimental group was provided with a peanut-shaped exercise ball. The ball was used to support maternal positioning that promoted spinal flexion; fetal head rotation; and widening of the pelvic inlet, outlet, and intertuberous diameter. Answer the following questions regarding this study. Tussey, C. M., Botsios, E., Gerkin, R. D., Kelly, L. A., Gamez, J., & Mensik, J. (2015). Reducing length of labor and cesarean surgery rate using a peanut ball for women laboring with an epidural. The Journal of Perinatal Education, 24(1), 16–24. doi:10.1891/1058-1243.24.1.16
