In ArgGIS 9.3 there is a function of ArcToolBox named Summary Statistics (Analysis).

I'm finding a similar function on QGis. One of these is Dissolve with stats (plug in) but on my version of QGIS (2.14.1 Essen) don't work... "local variable 'nElement' referenced before assignment See log for more details"

Message Log error: Traceback (most recent call last): File "C:/Users/Giuseppe Cillis/.qgis2/python/plugins\DissolveWithStats\dissolve_stats.py", line 71, in run self.dlg = dissolve_stats_dialog.DissolveWithStatsDialog(self.iface) File "C:/Users/Giuseppe Cillis/.qgis2/python/plugins\DissolveWithStats\dissolve_stats_dialog.py", line 98, in __init__ listRes = self.calculateFields(listKeep, listStats, output) File "C:/Users/Giuseppe Cillis/.qgis2/python/plugins\DissolveWithStats\dissolve_stats_dialog.py", line 274, in calculateFields listAttrs[uniqueValuesDissolveField.index(x)].append(y) ValueError: u'LAVELLO' is not in list

Instead, I tried it on an old version (QGIS 2.8 Wien) and it works.

Can i resolve this problem? Is there an alternative to Dissolve with stats?

You could to use the pluguin "Group stats".

This plugin works like a dynamic table in Excel!
