TABLE 10.1 Comparison of Standard Treatment and New Treatment for Ankle Sprains Class Activity, Part 1 An athletic trainer wants to compare two ankle sprain treatments on ankle swelling. We use the ratio of the mean difference to the standard error of the difference (SE), relative to the critical value found in Table A 3a to determine whether the means differ significantly. 41 1.
