Showing Statistics for Multiple Attribute using ‘Show Statistical Summary’ tool in QGIS

The GroupStats Plugin: Your Statistical Sidekick: This plugin is a lifesaver. Think of it as your go-to for generating statistical reports broken down by groups or categories within a field. It lets you calculate all sorts of stats – sums, averages, medians – for multiple attributes, all neatly organized by the values in another attribute field. The results pop up in a table, and you can even export them as a CSV file for some spreadsheet wizardry later on.

Batch Mode Stats by Category: Unleash the Power of Repetition: QGIS has a trick up its sleeve: running stats by category in batch mode. Basically, you can tell QGIS to run the same statistical analysis on a bunch of different fields, one after the other. Just add a row for each field you want to analyze, tell it which field to calculate the stats on, and then pick the field(s) you want to group things by. It’ll spit out a separate report for each field. Boom!

“Join attributes by location (summary)”: Spatial Stats, Simplified: Need to summarize stats based on where things are located? This tool is your friend. It calculates summary statistics for features based on their spatial relationship with other features. We’re talking counts, maximums, minimums, means, medians – the whole shebang.

Field Calculator: Your Data Tinkering Workshop: Don’t underestimate the power of the Field Calculator! It’s not just for simple calculations; you can use it to create entirely new columns based on formulas involving multiple existing columns. For example, you could add up the values from several columns into a single, combined column.

Dissolve with Stats / Aggregate Tool: Polygon Power Moves: Got polygon layers? The “Dissolve with Stats” plugin (or the built-in “Aggregate” tool) lets you merge polygons based on a shared attribute while simultaneously calculating statistics for other attributes. It’s perfect for summarizing data within those newly merged shapes.
