[Qgis-user] getting statistics from a raster layer

[Nick Hopton]

I think the first thing to do is clip the raster to your area of interest
using the vector polygon. Raster -> Extraction -> Clipper. Select the
polygon shapefile as the mask layer.

To get the statistics load the clipped raster, right-click on it in the
layers panel, select "Properties" and then click the "Metadata" tab. This
will show the mean, min, max and SD, but not (unfortunately) the median.
