I am using QGIS v 1.7.4 for MAC and I am trying to calculate mean coordinates for a set of points using ftools.
To calculate my result I am going to Vector -> Analysis tools -> mean coordinates and then getting a plot output to a new layer.
However, the point seems to be totally off, even if I filter out outliers in my original points set.
Furthermore, I've read it's possible to calculate both regular and weighted means but don't find this option anywhere.
