5.38 Meniscus: stiffness. An experiment was conducted to compare three different methods of repairing a meniscus (cartilage in the knee). Eighteen lightly embalmed cadaveric specimens were used, with each being randomly assigned to one of the three treatments: vertical suture, meniscus arrow, FasT-Fix. Each knee was evaluated on three different response variables: load at failure, stiffness, and displacement. The data are located in the file Meniscus. 18 For this exercise we will concentrate on the stiffness response variable (variable name stiffness). In Menisc a. Give the hypotheses that would be tested in an ANOVA procedure for this dataset. b. Show that the conditions for ANOVA are met for these data. c. Conduct an ANOVA. Report the ANOVA table and interpret the results. Do the data provide strong evidence i at the mean value of stiffness differs based on the type of meniscus repair? Explain.5.38 Meniscus: stiffness.
