Mass shootings in the USA 2013-2015
The definition of mass shootings used is that it is an incident were firearms are used and at least 4 people were shot at. They don't have to be killed.
The first chart we made was on the frequency of the magnitude of the mass shootings. So we summed the number of incidents per year according to the number of deaths.
There doesn't seem to be a trend in there.
Next, we counted the number of incidents according to the day of the week they happened. This shows clearly that shootings are more common in the weekend. And particulary the Sunday is popular.
