---|---|---|---|---|
Shots fired | Pistol incidents (n=165) | Revolver incidents (n=71) | Pistol incidents (n=165) | Revolver incidents (n=71) |
*Group means differed significantly for pistol and revolver cases. The t statistic = 3.11 (p<0.01) using minimum shots fired estimates; t statistic = 3.51 (p<0.01) using maximum shots fired estimates; t statistics were calculated using the formula for populations having unequal variances. | ||||
