## NAME

v.univar

## DESCRIPTION

v.univar calculates univariate statistics of vector map features. This includes the number of features counted, minimum and maximum values, and range. Variance and standard deviation is calculated only for points if `type=point` is defined.

Extended statistics adds median, 1st and 3rd quartiles, and 90th percentile.

## EXAMPLE

    g.region rast=elevation.10m -p
    v.random out=samples n=100
    v.db.addtable samples col="heights double precision"
    v.what.rast samples rast=elevation.10m col=heights
    v.db.select samples

    v.univar samples col=heights type=point
