Chapter 6: How Can I Miss You If You Won’t Leave? Regression Model Selection
The Virginia Polytechnic Institute did a study to try to estimate the distance 105
of a punt in football (something Ohio State fans aren’t familiar with). Possible
variables they thought may be related to the distance of a punt included the
following:
✓ Hang time (time in the air, in seconds)
✓ Right leg strength (measured in pounds of force)
✓ Left leg strength (in pounds of force)
✓ Right leg flexibility (in degrees)
✓ Left leg flexibility (in degrees)
✓ Overall leg strength (in pounds)

The data collected on a sample of 13 punts (by right-footed punters) is
shown in Table 6-1.
