>>I am in casa grande.. ? :-) Is this a statement or a question? heheh. > Good grief, man! Way to skew the results! ;^) results can be skewed by a lot of things. I could always just throw data out that sits beyond a certain reach. Such as finding the radius of a circle with downtown Phoenix at its center that gives me 95% coverage of the data points given. Or, as I suspect this data will show, an ellipse with two foci. I've gotten quite a few responses so far. I've got about 25 data points for a group of ~500 people based on the list subscription. I'll start up the map once I have more than 30 unique responses. Another point that has been brought up by responses is that the home address is just one focal point for an individual. The other might be their place of work. The only problem with collecting more than one point for a person is that they have a time dependency associated with them. These two points then only help if the map is drawn for a certain time of day (e.g. weekday just after work would use one point, the rest of the time would use the second as the focal point for the person). But I'm really not looking at making this into a statistics problem like you see in Numb3rs :) --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change you mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
