Mapping Deaths on Campus

Over the course of the outbreak, cholera-related deaths were reported around campus, and numerous crowdsourcing efforts were taken to effectively collect and report these points of data.  Of course, as with many collaborative platforms, the collected data is often unchecked and chaotic, as shown below in the final map created at the end of the five days.
From the data above, I extracted my own points as shown in the map below.  Each point represents a reported cholera-related death with each color corresponding to a day.  Unfortunately, I was unable to get to every point on campus, but one of the benefits of a collaborative approach to crisis response is that gaps can be filled quickly because of the number of people invested in the effort.
Based on the data above, I was able to create the map below, which shows some analysis of the data based on the density of points.  The more purple the region the higher the density. From looking at the map the two areas with the highest density are around Villard and the Frohnmayer Music Building, and there are two areas of moderate density around the Knight Library.  I would attribute the areas around Knight to it being an area of very high traffic normally, and so a moderate density of deaths around Knight is not statistically significant.  The high number of deaths around Villard and Frohnmayer, from a statistical point of view, could be considered significant as the level of traffic around those areas is significantly lower than the average level of foot traffic on campus because only theater and music majors respectively frequent those areas except when an event is going on.
Through this analysis, I can conclude that either the outbreak was started in either Villard or Frohnmayer, and this hypothesis is especially likely if there were any events scheduled in these two buildings over the course of the outbreak. That being said, my hypothesis further narrows to just the Frohnmayer building based on the locations of the deaths on the final day.
