[GIS] Calculating Standard Deviation in QGIS

qgisspatial statistics

Does anyone know of a way to find the standard deviation of an attribute lying within any given polygon?

The plugin dialog "Join Attributes by Location" gives only the options Mean, Min, Max, and Sum.

I'm using QGIS 1.6.0.

"Statist" plugin calculates StDev. It has a "use only selected features option".

You'll need to use "Select by location" first to select the features within your polygon-of-interest. Then run Statist.
