Designing footwear to improve posture. Refer to the Human Factors (December 2019) study on the effectiveness of designed footwear for elderly women, Exercise 15.34 (p. 15-24). Remember that data on range of center of pressure (COP) were collected for each of 24 elderly women under three foot conditions: barefoot (condition A), wearing a designed texture insole (condition B), and wearing a designed texture insole with an arch support. In Exercise 15.34, you compared the distribution of COP ranges for Conditions A and B, and then compared the distribution of COP ranges for Conditions B and C. Now conduct a single nonparametric test to compare the distribution of COP ranges for all three conditions. Use a = .05. What inference can you make?
