Name: Hope College Football Helmet Data

 

Abstract: This dataset looked at a new helmet facemask called Riddell Quick Release Face Guard System, which is designed to be removed quickly off the helmet in times of athlete injuries.  The new facemask was randomly assigned to Hope College football players, who were put into four groups in the Fall of 2008.  Group 1 was supposed to be evaluated all four times, group 2 was supposed to be evaluated three times, group 3 was supposed to be evaluated two times, and group 4 was supposed to be evaluated one time.  Sometimes this was not the case due to injuries or lost helmets.  A facemask was measured by how long it took the remover to remove it (in seconds).  If it took the remover less than 120 seconds to remove the facemask then the facemask passed (success), but if it took the remover more than 120 seconds then it was a failure.

  1. Group (1-4)
  2. Time for First group (seconds)
  3. Time for Second group (seconds)
  4. Time for Third group (seconds)
  5. Time for Fourth group (seconds)
  6. Time First Recode (0=Fail, 1=Success)
  7. Time Second Recode (0=Fail, 1=Success)
  8. Time Third Recode (0=Fail, 1=Success)
  9. Time Fourth Recode (0=Fail, 1=Success)
  10. Remover Time First (1=Person 1, 2=Person 2)
  11. Remover Time Second (1=Person 1, 2=Person 2)
  12. Remover Time Third (1=Person 1, 2=Person 2)
  13. Remover Time Fourth (1=Person 1, 2=Person 2)
