It is believed that hamstring tendon grafts have been the weak link in anterior cruciate ligament reconstruction. The following data presents the required force (in Newtons) at which initial failure of graft strands occurred for a sample of 12 cadaveric knees. 25.5, 130.0, 118, 85.6, 156.2, 180.0, 66.8, 92.3, 211.9, 114.4, 99.5, 73.5 a. Compute the mean and median. (1 Mark) b. Compute range and IQR. (2 Marks) c. d. Compute variance and standard deviation (SD).
