I would like to classify several values from a vector table with field calculator in 5 classes based on standard deviation. Example: value = 3.3, mean = 2.5, std deviation = 0.7 and class #5 is "mean+std dev and above", than his new value is 5 (new column)
It seems pretty easy to do with a CASE ELSE statement in QGIS, but I would like to write something that I can use for several SHPs with different means. I was looking for some help here to simplify the statement so it can be easily re-usable with a new and different shp.
Thanks!
