A big-toe problem.
Problem: Hallux abducto valgus (call it HAV) is a deformation of the big toe that is not common in youth and often requires surgery. Doctors used X-rays to measure the angle (in degrees) of deformity in 38 consecutive patients under the age of 21 who came to a medical center for surgery to correct HAV.16 The angle is a measure of the seriousness of the deformity. The data appear in Table 7.4 as "HAV angle."
Requirement:
1. Describe the distribution of the angle of deformity among young patients needing surgery for this condition.
