Beginner - hotspot analysis

I'm hoping this is a straightforward question to answer!


I am trying to do a hotspot analysis for a dataset of road accidents. I am using the OpenStreetMap as a basemap, and originally imported my dataset with the geographic coordinate system WGS 1984. However when I tried to perform hotspot analysis, it didn't work and told me that "the input feature class does not appear to contain projected data". So, I imported my data again using the projected coordinate system, World>WGS1984 Web Mercator (I didn't know which WGS 1984 to choose, there were a few!). However my data points now show that they are in Nigeria, not Scotland!


If anyone could help I would appreciate it so much, it is for my dissertation and I've been trying to figure out how to use hotspot analysis for months!


Kind regards,




p.s. I'm using ArcMap 10
