The results of an ANOVA revealed that the combination of a bullet’s mass and the relative velocity of the weapon is the most significant factor in entrance wound size. A logistic regression found that mass plays the most significant role in the presence of an exit wound. When considered separately, velocity had a more significant effect on exit type than did mass. The study also found that being male increases the odds that a firearm will be chosen to commit suicide. Handguns and the head were the most common choices for weapon and wound location, respectively, in both firearm suicides and homicides. / Committee in charge: Dr. John Lukacs, Chairperson; Dr. Andrew Karduna, Member; Dr. David Levin, Member
