So I'm new to this, the answer is probably really simple.
I have a point map of X Y data points (one for each participant) for a certain activity. I also have a shape file of zip codes, which I then made a point file out of this with the centroid for each zip code. I want to measure the distance from the point for the activity to the zip code that corresponds to each specific participant. I joined the attribute tables for these so that each participant has the a column for the lat, and long for the activity and the zip code lat and long. I must be close.
How do I ask ArcGIS to measure the distance between these points?
I'm using ArcMap 10.2.
