👉 The mean weapon, often referred to as the average weapon or mean lethal weapon, is a statistical measure that represents the expected number of lethal injuries caused by a specific type of weapon in a given population or scenario. It is calculated by summing the number of lethal injuries caused by each weapon in a sample and dividing by the total number of weapons used. For example, if a study finds that 10 out of 100 shots fired with a particular gun result in lethal injuries, the mean lethal weapon for that gun would be 10. This metric is crucial in various fields, including law enforcement, military strategy, and public health, as it helps in understanding the potential impact of different weapons and can guide decisions on weapon design, training, and policy.
